VRF

Define a VRF

vrf (VRF_NAME): Define a new VRF

Example :

n1(config)# vrf vrf-green

Add an interface to VRF

ip vrf forwarding NAME: Add interface to VRF NAME

no ip vrf forwarding [NAME]: Add interface to VRF default

Note

When adding/removing interface to VRF, make sure no valid IP is set on it

Example:

n1(config)# int ge3
n1(config-if)# ip vrf forwarding vrf-green
n1(config-if)# ip address 200.1.2.20/24

VRF Configuration examples

VRF Trunking

Example :

n1(config)# int ge1.100
n1(config-if)# encapsulation dot1q 100
n1(config-if)# ip vrf forwarding vrf-green
n1(config-if)# ip address 200.1.2.20/24
n1(config)# int ge2
n1(config-if)# rewrite tag push 1 dot1q 300

Dynamic routing in VRF

Example:

soodar3(config)# router ospf vrf vrf-green
soodar3(config-router)# network 200.2.3.0/24   area 0
soodar3(config-router)# network 3.2.1.0/24   area 0
soodar3(config-if) # end

VRF FIB

Example:

soodar1# sh ip ospf vrf vrf-green route
soodar1# sh ip fib vrf vrf-green
soodar1# sh ip fib vrf all

Display VRF info

show vrf

Example:

n1# sh vrf
vrf vrf-blue id 5 table 300

Logging

Debugging logs can be set in case of need.

[no] debug vrf event: logs data plane installation processes and results
