The response I got when I asked was that it was an "unintended feature". That may be the case but it was working just fine. I wish they'd add the feature. It's really important for 7600s that serve access functions along with core/distribution functions. The only other solution is to burn additional ports to separate the 1Q trunk between pairs of chassis for access VLANs (running a FHRP across the pair of 7600s) and a separate pair of interfaces for the L3 relationship between the chassis.

So I can only have BFD + eBGP if its on a physical port ?

Does the same apply to SVI + OSPF ?

Any known reason for this limitiation ?

(Waiting for my test 7606s to arrive!)

Hi, I'm looking at using BFD with BGP on 7600's (rsp720's and sup720-3b) and was wondering if there were any known issues with certain IOS's in the SRC or SRD train.

BFD support for SVIs was removed with SRB2 if that's something that you think you'll need.
