Query on VPC peer link and OSPF design

Unanswered Question
Aug 4th, 2011

Hello Experts,

I have a query on running VPC with two Nexus 7ks.

1>  VPC peer-link is made up of 2 dedicated 10g links. Can I have a peer-link , where link 1 is on one type of line card ( say N7K-M132XP-12L ) AND link 2 is on another type of line card ( say N7K-M108X2-12L ). would that work ?

2> Sounds like a basic ospf question. I am a bit confused to design an ospf network where the same subnet is kept in area 5 on 1 router and in area 6 on a different router. These two routers acting as ABR will  advertise these subnets into area 0.

Would there be any problem if i keep the area 5 and 6 side of interfaces as passive interfaces?

Any detailed response with the fundamental reason for any probable problem would be highly appreciated.

Thanks in advance,

Gazeddin

I have this problem too.

1. It should work if the port on the M132 is dedicated mode also. If I remember correctly, you cannot mix port-channel between dedicated mode and shared mode interfaces.

2. It will work if the the the backside is passive. It will cause a lot of confusion for sure. Why you want to do it this way?

HTH,
