My MPLS Cheat Sheet.

Below is a list of troubleshooting commands I comprised over the years while working for a “major telecommunications internet provider”. The commands helped me to easily isolate most MPLS issues that I came across.

show ip vrf interfaces | i <IP>
show run | run vrf <NUMBER>
show ip route vrf <NUMBER>
show ip bgp vpnv4 vrf <NUMBER>
show ip bgp vpnv4 vrf <NUMBER> summary
show ip bgp vpnv4 vrf <NUMBER> neigh <IP> policy
show ip bgp vpnv4 vrf <NUMBER> neighbor < IP> route
show ip bgp vpnv4 vrf <NUMBER> neighbor <IP> advertised-routes
show ip bgp vpnv4 vrf <NUMBER> neighbor <IP> advertised-routes | i <NETWORK IP>
show ip route vrf <NUMBER> < IP>
show ip b v v <NUMBER> <IP>
tr vrf <NUMBER> <IP>
ping vrf <NUMBER> <IP>

    • That’s a hard questions, you gotta go with what you like doing. Networking does take a slight programers role, if you consider some of the elaborate configurations that one must create to make traffic flow smoothly. I like networking I followed this not because I can make more money but because I honestly enjoy it,
