Greetings Team -
I am working on a small network and have some specific needs. I have excellent Cisco experience (especially in MPLS/Metro networks) but I am in need of guidance on this particular issue.
NEEDS: Company wants to be able to share VLANs from either site between sites.
REASON: I am validating their BC/DR plan, and as-is there are heavy routing changes which need to be made manually to bring up the DR site's VLAN102 and VLAN104. Both sites have identical VMware hosts and SAN's and data s replicated to the DR site in [near] real-time. Having the ability to have the DR site operate on a working VLAN102 and VLAN104 would GREATLY speed up the fail-over process.
BACKGROUND:
MY IDEAS:
I'm thinking VRF-lite would suffice for this - but need some guidance on if anyone can make this easier and/or less complicated?
I am open to suggestions!
Thanks,

Have you looked at Local Area Mobility?

I am not overly sure Local Area Mobility would be the correct solution for this. We are not looking for user mobility, simply we are looking the ability to continue to function seamlessly if one entire site catastrophically disappears.
Additionally, having the ability for our VLAN's to appear at both sites simultaneously is key (essentially so our mission critical servers can be started FIRST, and other servers can come up as replication finishes).
That being said, is LAM going to function properly if one site is completely unreachable.

Lam allows you to "roam" or in effect have the same ip range routable in a host format. Reading our response that is not the correct solution. If you MUST have the same VLAN/ip subnets in two physically separate locations then you should consider
Psudeo layer 2
Overlay transport virtualisation
Fabric path

Sean,
I have just been confronted with this SAME issue, and I have basically the same network setup except I have SUP IV's and I have a dedicated fiber link between campuses (roughly 27miles). It is VMWARE group requesting same IP/VLAN in the DR as the Main campus. Researching Andrew's response led me to believe the OTV & Fabric path were only available on Nexus 6500 ~ 7000. Please advise.
Thank you,
