[c-nsp] Loopback Interfaces and VRF configuration

[Maya Yajnik]

Hello All,

Thank you for the responses! I am referring to the example of VRF-Lite
configuration on the Cisco Catalyst 4500 series switches.

Here is the link.

That is just to simulate different VPN customer end points for reachbility
tests in examples.

 

Hope you are referring to the examples from Cisco site.

 

HTH-Cheers,

Swaroop

Hello

Does anyone know the purpose of using an additional Loopback interface (like
Loopback1) and associating that with a vrf? I see this in VRF-Lite example
configurations.



For example,

Router(config)# interface Loopback1
Router(config-if)# ip vrf forwarding v1
Router(config-if)# ip address 3.3.1.3 255.255.255.0
Router(config-if)# exit



Thank you!

Maya
