I understand that RT's are extended communities and how they work with importing and exporting into a VRF on PE rotuers. However, what I am confused about is the VPN label that is added when being transported through the MPLS domain. What I have gath...

I am looking for some ideas for the best way to tunnel layer 2 traffic. It would need to be very inexpensive and easy to setup/manage.Background:I work in a hospital where the network used to be completely layer 2 with about 130 VLANs. A couple of ye...

So something weird was happening when we were setting up a VPN connection yesterday (tunnel is up now and passing traffic). Here is a diagram of our topology:(10.26.0.0/16)--ASA-1-------------ASA-2--(192.168.1.0)So our tunnel didn't come up right awa...

I think what is happening is that edge 01 still has a default route in its routing table from edge 02 (while DIA 1 is offline), because it has that default route, it will continue to advertise its own default route.

I agree with you on this as the best option as it doesn't require a re-design of a lot of things. Thanks for the input!

" The "simplest" way to span VLANs across wiring closets? Bridge those VLANs at L2 from the closet access switches all the way across the Nexus switches. That is, do not terminate those VLANs into L3 on the access switches before transporting across ...

Here is the topology:We have roughly 20 closets connecting to the Nexus switches in this fasion, and they would all need to transport each VLAN. I said we have 130 VLANs, but I think only about 20 are actually used.

That's what I was originally thinking, but I think I confused myself with how it would be setup, specifically what to use as tunnel IP. If the Nexus were to receive say an ARP message, how would it know which tunnels to broadcast it to?
