Configuring OSPF SR Mapping Server with LDP
This chapter shows how to configure OSPF segment routing mapping server to work with LDP.
A segment routing mapping server allocates Segment Identifiers (SIDs) for prefixes and ranges of prefixes in an OSPF segment routing domain.
LDP can advertise SIDs for destinations in the LDP part of the network that does not support segment routing. These segments are converted to MPLS labels and installed in the FTN/ILM and forwarding tables.
OSPF uses OSPF TLVs to advertise any additional attributes associated with a prefix by adding new TLVs or sub-TLVs to the existing OSPF TLVs.
Note: Configure PE1 and PE2 router as a OSPF Segment routing, P1 and P2 router as a segment routing mapping server and PE3 and PE4 as a OSPF with LDP.
