Taking off OSPF and using L2 links.

The network I’m working on has a Cisco 6509 that is directly connected to 2 data center Nexus 7009 devices. OSPF is being used on the loopback and a vlan to communicate with the Nexus 7009 devices. On the 6509 switch BGP is configured and neighbored with core 6513 devices upstream from the Nexus 7K devices. I want to take routing off of the 6509. There is a Virtual Port Channel L2 going from the Cisco 6509 to the Nexus 7K devices. No other devices (router or switches) are connected to this 6509 except a few servers connected directly to ports on the 6509. I want to have L2 handle all the traffic to and from the servers and get rid of the routing.

I’m wanting to know what type of issues I could have by removing the OSPF routing and then possibly removing the BGP after that.

I would think that the layer 2 VPC going from the 6509 to the Nexus 7K switches would handle all the traffic better then OSPF over the L2 VPC. OSPF is running on the Nexus 7K devices upstream to the Cores that are running OSPF and BGP.

Note: Routing is not supposed to be done over a VPC and that is why I'm wanting to get rid of the routing.

Thank you,

You know the old saying: "A picture is worth a thousand words"?  This is an excellent example of that. :-)

I started drawing this out and then I hit the 6513 which is a BGP neighbor to the 6509 that is "upstream" of the N7K.  So is the 6509 between the 6513 and the N7K's or are the N7K's between the 6509 and the 6513?

I uploaded the diagram when I created this and again, but for some reason it's not getting through. It's a Visio document, this is the diagram changed to .jpgNetwork diagram, maybe this will work.

I can't see any problems with removing OSPF. But I think your motivation is flawed.

1st, the idea that vPC will have better distribution is debatable.   In the end, I don't know that you'll see improved distribution.

2nd, your topology with respect to OSPF & vPC is fine since you're not doing vPC over layer 3 links.

Don,

That is part of the problem, OSPF is running over VPC65 and OSPF is not fully forming the adjacencies on the 7ks , also I want to make everything L2 below the Nexus 7Ks and not have to break VPC 65 to get OSPF working correctly. I want to rremove OSPF completly from the 6509, another issue is BGP is running on the 6509 and neighboring to the 6513s.
