GRE Tunnel alternatives for 3750

RonaldNutter

Level 1

I am looking for alternatives to GRE since it isnt officially supported on 3750's.  I am dealing with a Managed MPLS situation where the carrier manages the routers at each site and I only have read-only access.

The carrier is resistant to making any changes to the router since it would be a one-off or deviation from their standard config.  What I am trying to do is to force all site traffic for our department coming from different locations to be forced all the way back to corporate and not "see" any of the other departments.  I am not concerned about encrypting the traffic but finding a way to route the traffic back to corporate since I am pretty much not able to make any router changes.

Thanks,

Ron

Hi,

if it is supported you could use an IP in IP tunnel.

Don't forget to rate helpful posts.

Beeing doing a little digging and found that the is a way to do ip over ip tunnel.

If I do enter int t0 at config mode prompt, I can then do tunnel mode ipip.

Since GRE isnt supported on a 3750, is IPIP supported ?

Havent seen any documentation one way or the other that it is or isnt.

Anybody familiar with this ?

Thanks,

Ron
