VRF and OSPF on Nexus 7k

[tinhnho123]

Hello guys,

I've seeb a configuration on one of my Nexus 7009 switches:

vrf context Blue

vlan 132
no shutdown
vrf member Blue
ip address 192.168.2.1/25
ip router ospf 1 area 0.0.0.0

vlan 133
no shutdown
vrf member Blue
ip address 192.168.4.1/25
ip router ospf 1 area 0.0.0.0

router ospf 1
router-id 10.10.10.1
vrf Blue
    auto-cost reference-bandwidth 1 Gbps

I was wondering why do we need ospf here since we already have vrf? Am I missing something?

Thanks.

• A VRF instance is configured under an OSPF instance (Numerous VRF instances can be associated to a single OSPF instance). In Cisco IOS Software, a VRF instance is associated to a single OSPF process in a one-to-one relationship.
