A life with Cisco VRFs



Without going into much details a a VRF is splitting a router virtually into independent ones.

For more information click here.

When it comes to it's configuration is pretty similar as what you will do normally, but just adding the vrf keyword... most of the time is pretty intuitive but sometimes the commands are completely different and for my own personal reference I decided to have this post as a reminder of a few tricky commands.


Regular commands
VRF aware commands
ping 8.8.8.8
ping vrf INTERNET 8.8.8.8
show ip route
show ip route vrf INTERNET
