NEW QUESTION 11
Which statement about the use of Route Target Rewrite is true?

  • A. It is mainly used in Intra-AS MPLS VPN deployments and is configured at the ASBR to avoid misconfiguration of the Route Target assignment for VPN configurations.
  • B. It is mainly used in Inter-AS MPLS VPN deployments and is configured at the ASBR to avoidmisconfiguration of the Route Target assignment for VPN configurations.
  • C. It is mainly used in Intra-AS MPLS VPN deployments and is configured at the Router Reflector to avoid misconfiguration in Route Target assignment for VPN configurations
  • D. It is mainly used in Inter-AS MPLS VPN deployments and is configured at the Router Reflector to avoid misconfiguration of the Route Target assignment for VPN configurations
  • E. It is mainly used in Inter-AS MPLS VPN deployments and is configured at the PE router to avoid to misconfiguration of the Route Target assignment for VPN configurations

Answer: B

Explanation: The MPLS VPNā€”Route Target Rewrite feature allows the replacement of route targets on incoming and outgoing Border Gateway Protocol (BGP) updates. Typically, Autonomous System Border Routers (ASBRs) perform the replacement of route targets at autonomous system boundaries. Route Reflectors (RRs) and provider edge (PE) routers can also perform route target replacement. The main advantage of the MPLS VPN - Route Target Rewrite feature is that it keeps the administration of routing policy local to the autonomous system.

  • E. TTL Security Check

Answer: E
