Reuse threshold—Arbitrary value below which a suppressed route can be used again.
Suppress penalty
Cutoff (suppression) threshold—Arbitrary value above which a route can no longer be used or included in advertisements.
Max suppress time
Maximum hold-down time for a route, in minutes.
Un-reachability Half-Life time
Number of minutes after which an arbitrary value is not halved if a route stays stable.
Max penalty (ceil)

Route Entry Examples
*> 2002:58::/32 fe80::202:b3ff:fec8:9fdb 0 20 i
This route entry shows that this route is learned from eBGP.
The origin code “i” means that the prefix is added by the network statement at originating AS.
The path 20 indicates that the prefix advertisement originated from AS20.
The administrative weight parameter applies only to routes within an individual router.
Since this route was learned from a peer, it has a default weight of 0. All routes generated by the local router have a weight of 32,768.
*> 2001:58::/32 fe80::202:b3ff:fec8:9fdb 0 20 ?
This route entry shows that the prefix is learnt from eBGP.The origin code i indicates that the prefix is added by network statement at originating AS.The path attribute 20 indicates that the route advertisement originated from AS20.The administrative weight parameter applies only to routes within an individual router. Since this route was learned from a peer, it has a default weight of 0. All routes generated by the local router have a weight of 32,768.The origin code “?” means the route was learned through redistribution.
*>i2003:58::/32 fe80::208:a1ff:fe16:797d 100 0 i
The status code “i” means that the route was learned through iBGP. The Local Preference attribute of the route, which is used only with the local AS, is set to 100 (the default value).
Example: IPv6 Prefix Routes
This example shows labeled routes for a given IPv6 prefix:

BGP Neighbor Fields
 
Table 4-59 explains the output fields.
 
Table 4-59: show bgp neighbor output details
Field
Description
BGP neighbor
BGP session information for the neighbor with the ip-address argument.
remote AS
Remote Autonomous system used to exchange exterior routing information between neighboring ASs.
local AS
Local Autonomous system used to exchange internal routing information within AS.
internal link
external link
Internal link is used to forward route advertisements received from an external BGP router through the internal network (in the same AS).
External link is used for exchanging routing information between Autonomous Systems (AS) and routing traffic across the Internet (eBGP neighbor).
member of peer-group
Peer group information for the peer group specified with the peer-group argument.
BGP version
Negotiated BGP version for this session.
remote router ID
IP address of the neighbor. BGP uses the highest loopback address as the Router ID. If no loopback interface is configured, BGP uses the highest configured IP address on a system.
BGP state
Session state as explained in Table 4-64. The exchange of routing information begins between peers only after the neighbor session is in an Established state.
up for
Time that the underlying TCP connection has been up.
last read
Time since BGP last received a message from this neighbor.
hold time
Time, in seconds, that BGP will maintain the session with this neighbor without receiving messages.
The maximum time that can elapse between successive messages from this neighbor is 180 seconds. If no message is received for 180 seconds, this neighbor will be declared dead.
last write
Time since BGP last sent a message to this neighbor.
keepalive interval
Time interval, in seconds, at which keepalive messages are transmitted to this neighbor.
The time interval between successive keepalive messages is 60 seconds. Typically, the hold time value is set to three times the keepalive interval.
neighbor capabilities
BGP capabilities advertised and received from this neighbor. “Advertised and received” is displayed when a capability is successfully exchanged between two routers.
received
Total number of received messages.
notifications: Number of notification (error) messages received.
in queue: Number of messages in the input queue
sent
Total number of sent messages.
notifications: Number of notification (error) messages sent.
in queue: Number of messages in the output queue
route refresh request
Number of route refresh request messages sent and received.
minimum time between advertisement runs.
The minimum time gap, in seconds, between successive route updates sent to the neighbor.
Generally, a jitter (of 25%) is applied to this time interval, which means that if the time between advertisements is configured as 30, successive advertisements can have a time gap of as low as 22.5 (after applying a 25% jitter to the 30 seconds, which is 7.5 seconds).
for address family
The peers have exchanged address family capability.
BGP table version
For each of the address families agreed upon, BGP maintains a separate table.
neighbor version
Tracks prefixes that have been sent and those that need to be sent.
connections established
The number of times the router has established a TCP connection and the two peers have agreed to speak BGP with each other.
“Dropped” means the number of time the connection has failed or gone down.
local host
foreign host
Local host is the IP address and the port number of the local system used for the peering session.
Foreign host is the IP address and the port of the neighbor.
BGP always uses the TCP port number 179 for the peer originating the session.
nexthop
The IP address of the next hop used to reach the neighbor.
eBGP or iBGP peers do not need to be directly connected. Peering sessions can be set up across multiple hops. If the neighbors are directly connected, the IP address of the local system is listed as the next hop.
nexthop global
The global IPv6 address of the next hop
nexthop local
The link-local IPv6 address of the next hop
non shared network
The peering session is running on a non shared network.
last reset
Time since this peering session was last reset. The reason for the reset is displayed on this line.
notification error message
Last error message sent.

Neighbor Entry Fields
Table 4-64 explains the fields for each neighbor entry.
 
Table 4-64: neighbor entry fields 
Field
Description
Neighbor
IP address of peer.
V
BGP version of peer.
AS
Autonomous system number of peer.
MsgRcvd
Messages received since the BGP connection was established.
MsgSent
Messages sent since the BGP connection was established.
TblVer
Last version of the local router’s BGP database advertised to the peer.
InQ
Received messages waiting in the input queue for further processing.
OutQ
Messages waiting in the output queue to be sent.
Up/Down
Connection up time and down time.
State/PfxRcd
If the TCP session is up and the BGP peers have formed an adjacency, this field shows how many prefixes have been received from the remote neighbor.
 
Other states:
 
Idle: The local router has not allocated resources for the peer connection, so incoming connection requests are refused
 
Idle (Admin): The peer has shut down
 
Idle (PfxCt): Prefix overflow
 
Idle (G-shut): Graceful shutdown
 
Connect: BGP is waiting for the TCP connection to complete
 
Active: the local router is trying to establish a TCP connection to the remote peer. You might see this if the local peer has been configured, but the remote peer is unreachable or has not been configured.
 
OpenSent: BGP is waiting for an open message from its peer
 
OpenConfirm: BGP received an open message from the peer and is now waiting for a keepalive or notification message. If BGP receives a keepalive message from the peer, the state changes to established. If the message is a notification, the state changes to idle.
 
Established: BGP is ready to exchange update, notification, and keepalive messages with its peer
 
Invalid: The session state is invalid

Status code
Description
Comments
s
suppressed
Whether the route is suppressed and will not be advertised to the neighbors.
d
damped
When the penalty of a flapping route exceeds the suppress limit, the route is damped and remains in a withdrawn state until its penalty decreases below the reuse limit.
h
history
When the penalty of a flapping route does not exceed the suppress limit, the route is not damped and BGP maintains a history of the flapping route.
p
stale
When the BGP neighbor from which a route is learned is in graceful restart, the route is retained in the BGP routing table, but marked as stale.
*
valid
Whether the route is valid. When a route is not suppressed, damped, or present in the history, it is valid.
>
best
The route selected as the best path and installed in the kernel routing table.
i
internal
Whether the route is learned from an iBGP peer. If this symbol is not present, the route was learned from an eBGP peer.
Origin codes: i - IGP, e - EGP, ? - incomplete
Table 4-66 explains the codes are at the end of each routing entry that show where the route originated.
 
Table 4-66: origin codes
Origin code
Description
Comments
i
IGP
The route originated from an Interior Gateway Protocol.
e
EGP
The route originated from an Exterior Gateway Protocol.
?
incomplete
Origin not known. Typically, these are routes redistributed from an Interior Gateway Protocol.
Route Entry Fields
Table 4-67 explains the fields shows for each route.
 
Table 4-67: route entry fields 
Field
Description
Network
Network prefix installed in BGP. If multiple routes exist for the same prefix, only the first prefix is identified and others have blank spaces.
The status codes are explained in Table 4-65.
Next Hop
IP address of the nexthop for this route.
Metric
Multiple-Exit Discriminator (MED). If there are multiple paths to the same destination from a single routing protocol, then the multiple paths have the same administrative distance and the best path is selected based on this metric. The path with the lowest metric is selected as the optimal path and installed in the routing table.
LocPrf
Local preference set with the set local-preference command. This value is used only with iBGP sessions within the local autonomous system to determine if a route towards a destination is the “best” one. The path with the highest local preference is preferred.
Weight
This field applies only to routes within an individual router. If a route was learned from a peer, it has a default weight of 0. All routes generated by the local router have a weight of 32,768.
Path and origin
The autonomous systems through which the prefix advertisement passed.
The origin codes are explained in Table 4-66
Route Entry Examples
*> 172.16.1.0/24 10.10.10.78 0 1 4 i
The absence of status code “i” means the route is external and was learned from an eBGP peer.
The “>” means this route is selected to be installed in the kernel routing table. Its network address is 172.16.1.0/24.
The IP address of the nexthop for this route is 10.10.10.78.
This route was learned from a peer, so it has a default weight of 0.
The path “1 4” means the prefix advertisement passed through AS1 and AS4.
The origin code “i” means the prefix was added by a network statement at an originating AS.
*> 192.16.1.0 10.10.10.78 200 0 1 4 ?
* 10.100.0.62 100 0 3 4 ?
The same prefix was learned from two different ASs, AS1 and AS3.
The route learned from AS1 is chosen as the best route because AS1 has a lower Router ID (10.10.10.78) than AS2 (10.100.0.62). Although the metric of the route learned from AS1 is higher (200) than the route learned from AS3 (100), this attribute is not used in the best path selection decision because the metrics are compared only if the first (neighboring) AS is the same in the two paths.
The origin code “?” indicates that the routes were learned through redistribution.
*>i192.17.1.0 10.100.0.62 100 0 i
The route is learned through an iBGP peer as indicated by the status code “i”.
The preference of the route, used only with the local AS, is 100 (the default value).

Field
Description
BGP neighbor
Router ID of the BGP neighbor.
remote AS
Autonomous system number of the neighbor.
local AS
Autonomous system number of the local system.
internal link
internal link: iBGP neighbor (in the same AS).
BGP version
The version of BGP being used by the neighbor device.
BGP state
The current state of the neighbor connection and length of time within the current state.Possible states are: Idle, Connect, Active, and Established.
Last read
The amount of time in Hours : Minutes : Seconds since this device last checked the Hold Time parameters.
hold time
The amount of time this device waits for a Keepalive or Update message before the BGP connection is closed.
Keepalive interval
KEEPALIVE messages are sent periodically to ensure that the connection is live.
Neighbor capabilities
New or optional parameters called “Capabilities.” Provides a graceful way to advertise new or unique options without causing peering to terminate. The capabilities are communicated in TLV fields. (see RFC 3392).
 
In the example output above, the following capabilities were advertised by the neighbor and were received and understood by this device:
Route refresh
Address family IPv4 Unicast
Address family IPv6 Unicast
Received
Message count, notification count, number of messages waiting in the queue.
Sent
Message count, notification count, number of messages waiting in the queue.
Route refresh request
Route requests sent and received.
For address family
As stated – in this case IPv4 Unicast.
BGP table version
For each of the address families agreed upon, BGP maintains a separate table.
neighbor version
Tracks prefixes that have been sent and those that need to be sent.
connections established
The number of times the router has established a TCP connection and the two peers have agreed to speak BGP with each other.
“Dropped” means the number of time the connection has failed or gone down.
local host
foreign host
Local host is the IP address and the port number of the local system used for the peering session.
Foreign host is the IP address and the port of the neighbor.
BGP always uses the TCP port number 179 for the peer originating the session.
nexthop
The IP address of the next hop used to reach the neighbor.
eBGP or iBGP peers do not need to be directly connected. Peering sessions can be set up across multiple hops. If the neighbors are directly connected, the IP address of the local system is listed as the next hop.
nexthop global
The global IPv6 address of the next hop
nexthop local
The link-local IPv6 address of the next hop
non shared network
The peering session is running on a non shared network.
last reset
Time since this peering session was last reset. The reason for the reset is displayed on this line.
notification error message
Last error message sent.
