ME3400
ME3400 is able to tunnel l2 protocols with the command "l2protocol-tunnel xxx"
Tunneled STP BPDUs have 01-00-0C-CD-CD-D0 as a destination mac-address
7600
On 7600 when using service instances on ES cards there is only one option, l2protocol forward.
As the name implies, the router does not alter the BPDUs. It just forwards them on the bridge domain bypassing the SP.

Following these different approaches, they can't interoperate in any easy way..
I think that we have the same issues. I read somewhere that L2PT support on ES cards was included in 15.3S, but can't see anything in release notes. Trying to verify.
ReplyDeletei also heard that in IOS 15.3 they support Tunneling. I have to try it though.
