Configuring OSPF Intra-Area Segment Routing
This chapter shows how to configure segment routing between routers in the same area.
The segment routing capabilities of a router are advertised to other routers through the Router Information opaque LSA.
Prefix SIDs are advertised through the Extended Prefix opaque LSA which supports multiple Extended Prefix TLVs containing subTLVs to carry the prefix and corresponding SID information.
Topology
Figure 4-4 shows the configuration required to enable OSPF segment routing at a global level and configure a prefix SID at the interface level.
You can configure a prefix SID on any router directly attached to that network prefix. In most cases configuring only one router is sufficient. If a prefix SID with the same prefix is configured on different routers, IP Infusion Inc. recommends that all SID values be the same.
OSPF Intra-Area Segment Routing Topology
Note: You must ensure that prefix SIDs are globally unique. Do not configure the same SID on different prefixes.

Verify that segment routing is enabled and that prefix SIDs are announced to other routers via OSPF opaque LSAs.
Verify that labels are in the MPLS forwarding table and that prefix SIDs are installed. Verify the same in FTN and ILM tables.

Segment Routing MPLS OAM
Segment Routing Operations, Administration, and Maintenance (OAM) helps service providers to monitor label-switched paths (LSPs) and quickly isolate forwarding problems to assist with fault detection and troubleshooting in the network.
The Segment Routing OAM feature provides support for FEC (forwarding equivalence classes) LSP Ping and Traceroute, IGP prefix SID FEC type, and partially IGP adjacency-SID FEC.
The following are the main benefits of Segment Routing-OAM Support:
• Operations: Network monitoring and fault management.
• Administration: Network discovery and planning.
• Maintenance: Corrective and preventive activities, minimize occurrences and impact of failures.
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 Traceroute
The MPLS LSP traceroute is used to isolate the failure point of an LSP. It is used for hop-by-hop fault localization 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).
Kindly refer Figure 4-4
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.
