Hi,
I have a pair of Nexus setup for VPC and ospf. Based on the Cisco VPC best practice on http://www.cisco.com/c/dam/en/us/td/docs/switches/datacenter/sw/design/vpc_design/vpc_best_practices_design_guide.pdf on page 78, I was wondering for a point to point layer 3 backup path link is created between the 2 switches, what would be the recommended way to form ospf between them but not to inject the route into the network. It should only be learned between both the nexus switches only. I have illustrated it below:
-------------------------10.0.0.0/24(Area 10)----------------------------------------------------
| |
Nexus Switch -----backup routing path(192.168.1.0/30)----Nexus Switch
Not too sure what would be the recommended approach for both the Nexus switch to have a layer 3 direct point to point route without injecting 192.168.1.0 into ospf area 10.
I was thinking of a separate ospf process only for the point to point backup link due to its simplicity however not too sure if it may be good?
Any suggestion is apprecated.
Thanks.
