Description Matthew Galgoci 2001-11-29 16:43:28 EST
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:
Comment 1 Matthew Galgoci 2001-11-29 16:51:30 EST
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.
Comment 2 Matthew Galgoci 2001-11-29 17:24:02 EST
Tested with all current errata as of 2001-11-29, same results as with stock
components
Comment 3 Matthew Galgoci 2003-02-27 22:23:49 EST
we are using zebra and cipe now. this appears to have been resolved.
