Hi,

I have two pair of Nexus7000 in my two datacenters as vPC pair (A&B in datacenter 1 and C&D in datacenter2 ).I have created VLAN 100 on all four Nexus with ip 10.1.1.2,.3 and .4. ip 10.1.1.1 is glbp and acting as GW for all my servers in both datacenters.Now my challange is , how can I keep my servers in 1st datacenter to use local Nexus's mac glbp as GW instead of using glbp mac of another Nexus in datacenter 2.

We would like to keep traffic local and achive loadblancing as well without using two GW address.

Any suggestions?

Regards.

Parhaps a late response.

Have you tried filtering the GLBP traffic between the two DC's so that the GLBP negotiation remain local within a site and each site elect a local primary.

Config similar to the following might work. But I have not tried it...

mac access-list GLBP-MAC

  1 deny any 0007.b400.0000 ffff.ffff.0000

  2 permit any any

interface e2/1

  mac port access-group GLBP-MAC
