 The router RA is configured with the command “ip pim ssm default”. This configuration enables Source-Specific Multicast (SSM) for the default range of 232.0.0.0/8, which is the IPv4 multicast address space reserved for SSM by IANA (Internet Assigned Numbers Authority). In SSM, data traffic is delivered to a specific group of subscribers identified by the combination of both source and multicast addresses, enhancing efficiency and security. References: Implementing and Operating Cisco Service Provider Network Core Technologies

The correct command to authenticate the OSPF neighbor between PE-A and PE-B using MD5 is found in Option A. In this option, the command ip ospf message-digest-key 1 md5 44578611 is used to configure OSPF MD5 authentication on an interface with the key ID as 1 and key string as 44578611. The second command ip ospf authentication key-chain 44578611 is used to enable OSPF authentication on an interface and associate it with a specific key chain. References := Cisco - Implementing and Operating Cisco Service Provider Network Core Technologies

The PSID plays a crucial role in segment routing, allowing efficient forwarding of packets along predefined paths.

For more detailed information, please refer to the official Cisco documentation on Segment Routing and IPv6. Unfortunately, I cannot directly cite specific pages from the provided resources, but you can find relevant details in the Cisco documentation.

OSPFv3 is used for routing IPv6 prefixes and requires that each interface intended to participate in OSPFv3 has the protocol enabled. This involves specifying the OSPF process ID and the area ID that the interface belongs to. The process ID links the interface to a specific OSPFv3 process running on the router, and the area ID determines the area within the OSPF topology that the interface is part of. Without this configuration, the interfaces will not actively participate in OSPFv3 route advertisement or neighbor relationships12.

 In the given scenario, to ensure that area 15 traffic from R5 to R1 prefers the route through R4, a multiarea adjacency should be implemented on the link between R2 and R4. The cost can be manipulated to make this path preferred. Multiarea adjacency allows OSPF routers to form adjacencies with routers in other areas, enabling more direct routing of traffic. By adjusting the cost of this adjacency, traffic can be directed preferentially through specific paths.
