Configuring OSPFv6 Segment Routing IPv6
This chapter contains configurations of SRv6 with OSPFv6.
SRv6
SRv6 represents Segment routing (SR) with IPv6 data plane. The SRv6 network program is encoded in the Segment Routing extension Header (SRH) of a network packet as an ordered list of segments. The most significant bits of a segment are called “locator”. The locator acts as any routed subnet address and ensures that the packet destined for a segment is routed to the destination of that segment. The packet goes from node to node and receives sequential processing according to ordered instructions selected by the source and encoded in the SRH. No intermediate node changes the flow.
Topology
Below example shows the SRv6 with OSPFv6 configurations.
