Applicability
This command was introduced before OcNOS version 1.3.
Example
#show ip bgp dampening dampened-paths
BGP table version is 32, local router ID is 3.3.3.3
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,l - labeled, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network From Reuse Path
d 11.11.11.0/24 90.90.90.1 00:27:20 200 i
Table 7-6 shows the status codes displayed at the start of a route entry.
Table 7-6: Status details
Status Code | Description | Comments |
|---|
s | suppressed | Whether the route is suppressed and is not advertised to 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d | damped | When the penalty of a flapping route exceeds the suppress limit, the route is damped and remains in a withdrawn state until its penalty decreases below the reuse limit.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 selected route to be installed in the kernel routing table. |
i | internal | The prefix was learned from an iBGP peer. |
Table 7-7 shows the codes at the end of each route entry that indicate where the route originated.
Table 7-7: origin details
Origin Code | Description | Comments |
|---|
i | IGP | The route is from an Interior Gateway Protocol. |
e | EGP | The route is from an Exterior Gateway Protocol. |
? | incomplete | Origin not known. Typically, these are routes redistributed from an IGP. |
Table 7-8 explains the output fields.
Table 7-8: show bgp dampening dampened-paths output details
Field | Description |
|---|
Network | Internet address of a network. |
From | IP address of the advertising peer. |
Reuse | The amount of time remaining until this route will be un-suppressed and can be used again. |
Path | Autonomous system path to the destination network. |
