The VPN named my_vpn is operating on interface s0/0 of a PE-router. The CE-PE routing protocol
is BGP.
The MPLS backbone IGP is OSPF. How should you verity routing information is being exchanged
between the PE-routers that support this VPN?
A.
On the local PE-router, you use the show ip cef vrf command and verify that there is a label for
the remote
PE-router’s next-hop.
B.
On the local PE-router, you use the show ip bgp summary command and verify that the BGP
session to the remoter PE-route is up.
C.
On the local PE-router, you use the show ip bgp vpn4 command and verify that routes from the
remote PErouter have been received.
D.
From the CE-router, you use the pint vrf command to ping the remote CE-router. If the CErouters cannot ping each other, then the PE-routers are not exchanging routing information.
Explanation:
To display VPN address information from the BGP tabl, use the show ip bgp vpnv4 command in
EXEC mode.
