PE-2 should import the OSPF route from the global routing table into the CUSTOMER-ABC VRF. This allows the VRF to have internet reachability.

The configuration should include an import route-target statement under the VRF configuration on PE-2. The route target should match the one used by CE-1 to advertise the default route (0.0.0.0/0) to PE-1.

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.

The configuration snippet shows a BGP router with AS number 65001. It has a neighbor at IP address 10.10.10.1 with remote AS number 4282, and there is an outbound distribute-list applied to this neighbor relationship (distribute-list 1 out).

The distribute list refers to access list 1, which permits any route with an AS path that starts with the local ASN (permit ^$). This means that only local routes will be advertised to the neighbor at IP address 10.10.10.1; routes from other Autonomous Systems (ASNs) will not be advertised because they would have an AS path starting with another ASN.

The issue here is that R1 and R2 cannot yet establish an LDP TCP connection. From the exhibit, it’s clear that the password is not required as it states “Password: not required, none, in use”. So, option C “Configure the no mpls Idp password option 1 command on R2” would be the correct answer to allow the establishment of an LDP TCP connection without requiring a password. This aligns with Cisco’s guidelines on configuring MPLS LDP where passwords might not be necessary for establishing connections between routers.

 The configuration in Option D is correct for implementing BGP selective prefix suppression according to the requirements. The “aggregate-address” command is used to configure the advertisement of the summarized route 10.16.0.0/21, and the “suppress-map” option allows for selective suppression of specific prefixes, in this case, 10.16.6.0/24. References: Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) - Cisco SPCOR Training & Certification

The failure to implement IS-IS multitopology can be attributed to the routing process not supporting extended metrics. Extended metrics are necessary for multitopology routing because they allow for the definition of multiple topologies within the same routing protocol, each with its own set of metrics and paths1.
