JN0-363 Exam Dumps : Service Provider Routing and Switching, Specialist (JNCIS-SP)

The adjacency SID in segment routing is advertised by one router to inform another about the label that should be used to forward traffic to it over a particular link. In this scenario, Router B would advertise an adjacency SID to Router A, which would be usedby Router A to forward traffic to Router B. Based on the exhibit, the adjacency SID that Router B advertises to Router A would be 12.

The flow label is a new field added to IPv6 headers that was not present in IPv4 headers. It is used to identify packets that require special handling by routers, particularly for quality-of-service (QoS) purposes.References:

In an MPLS network, the types of routers include ingress routers (where the MPLS labels are first applied), egress routers (where MPLS labels are removed), and transit routers (which switch MPLS-labeled packets through the MPLS network). Peering routers andaggregation routers are not specific types of MPLS routers; they are general network terms.
