Afternoon,
I'll soon be implementing VRF lite. The proposed design has multiple instances of VRF and each one will be using OSPF. Each instance of VRF will be using OSPF area 0. There will be apprx. 5 seperate OSPF processes, 1 for each VRF table.
We're not routing across a 3rd party network, effectively these are end to end L2 Vlans.
As we already have an OSPF backbone, i was wondering if having 5 more backbone areas is a recommended practice? The VRF OSPF routes will not be part of our normal OSPF process.
