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 avoid
misconfiguration 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

Explanation:
The MPLS VPN—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.
