A.

Establish full mesh IBGP peering with ail routers in different IGP domains.

B.

Redistribute different IGP domain routes in a BGP IPv4 routing instance.

C.

Transport site routes using a BGP VPNv4 address family on the PE routers.

D.

Apply BGP policies on all routers to filter out ABR and PE loopback IP addresses.
