Description of Problem: When using zebra on a linux router that includes cipe interfaces in the zebra config, zebra will fail to start on the first attempt with the following error: "cannot create router advratisement socket: Address family not supported" Subsequent attempts to start zebra will succeed. If you stop zebra and the cipe interface (leaving kernel module loaded), start the cipe interface again, and then attempt to start zebra, zebra will succeed. Only if you stop zebra, and cipe, remove the cipcb module, start cipe, and attempt to start zebra will it fail again. Version-Release number of selected component (if applicable): All components are stock Red Hat Linux 7.2. I will attempt to reproduce this with all errata applied, but I don't think cipe changed much from stock to errata. Straces of failures are on the way, How Reproducible: Very. Steps to Reproduce: . (see description ). Actual Results: Expected Results: Additional Information:
Attempted the same with ipv6 module loaded , net result is the same, but the error message: "cannot create router advratisement socket: Address family not supported" is NOT printed to stderr.
Tested with all current errata as of 2001-11-29, same results as with stock components
we are using zebra and cipe now. this appears to have been resolved.
