Configuring ISIS Segment Routing
This chapter shows how to configure segment routing using ISIS. ISIS uses ISIS-TE TLVs to advertise any additional attributes associated with prefix by adding new TLVs or sub-TLVs to the existing ISIS-TE TLVs.
These segments are converted to MPLS labels and installed in the FTN/ILM and forwarding tables.
Topology
•	“L1” means ISIS routers in Level-1
•	“L2” means ISIS routers in Level-2
•	“L1/L2” means ISIS routers in both Level-1 and Level-2
You can configure a prefix SID on any router directly attached to that network prefix. 
ISIS Segment Routing Topology
Note:	 
1.	Users must ensure that the prefix SIDs are globally unique. 
2.	Pure L1 or L2 routers can be used throughout the SR domain.

Validation 4
Verify that segment routing is enabled and that prefix SIDs are announced to other routers.
Verify that prefix SIDs are installed as labels in MPLS forwarding table. Verify the same in FTN and ILM tables.

In the forwarding tables above, the configured prefix SIDs are in the Out-Label column which is expected and is global across the topology. The swap happens in between nodes with this prefix SID and there is no local labelling.
Also verify the ILM and FTN tables.

Segment Routing Ping and Traceroute
Segment Routing Ping
The MPLS LSP ping feature is used to check the connectivity between ingress and egress of LSP. MPLS LSP ping uses MPLS echo request and reply messages, similar to Internet Control Message Protocol (ICMP) echo request and reply messages, to validate an LSP. 
Segment routing ping is an extension of the MPLS LSP ping to perform the connectivity verification on the segment routing control plane.
Segment Routing ping can use either generic FEC type or SR control-plane FEC type (ISIS-SR or OSPF-SR)
Segment Routing Trace
The MPLS LSP traceroute is used to isolate the failure point of an LSP. It is used for hop-by-hop fault locali-zation and path tracing. The MPLS LSP traceroute feature relies on the expiration of the Time to Live (TTL) value of the packet that carries the echo request.
Similar to segment routing ping, you can initiate the segment routing traceroute operation only when Segment Routing control plane is available at the originator
Segment Routing traceroute can use either generic FEC type or SR control-plane FEC type (OSPF-SR or ISIS-SR).
Validation
These examples show how to use segment routing ping to test the connectivity of a segment routing control plane and segment routing trace to trace LSP of specified Prefix SID.
Ping with other options.
