Verifying The Pe To Pe Routing Protocols - Cisco 10000-2P2-2DC Software Configuration Manual

Chapter 3 Configuring Remote Access to MPLS VPN

Verifying the PE to PE Routing Protocols

Border Gateway Protocol (BGP) is used for routing sessions between PE routers. To verify PE to PE
routing sessions, enter any of the following commands in privileged EXEC mode:
Command
Router# show ip bgp neighbors
Router# show ip bgp vpnv4 all
Router# show ip bgp vpnv4 vrf vrf-name
Router# show ip bgp vpnv4 vrf vrf-name ip-address
Example 3-24 show ip bgp vpnv4 all Command
Router# show ip bgp vpnv4 all
BGP table version is 17, local router ID is 192.168.1.2
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal
Origin codes: i - IGP, e - EGP, ? - incomplete
Route Distinguisher: 100:1 (default for vrf vrf-1)
