Step 3 Check the destination for a BGP address by entering the show ip bgp vpnv4 vrf command with the VRF
name.
8540-ATM-PE1# show ip bgp vpnv4 vrf 1
BGP table version is 164, local router ID is 102.0.0.2
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal
Origin codes: i - IGP, e - EGP, ? - incomplete

Step 4 If the routing protocol used on the customer side does not use BGP, enter traditional show commands,
and apply them to the correct VRF.
For example, if your network is using the Routing Information Protocol (RIP), enter the show ip rip
database vrf command.
Switch# show ip rip database vrf vrf101

Step 5 If you are using OSPF, you must enter the show ip ospf [process-id area-id] database command and
specify the correct process number. For example:
Switch# show ip ospf 2 database
