Hi Geir,
Does anyone have any experience with BFD on 12.2(33)SR?
We have troubles with BFD in a mixed 12.2(18)SXF7 and 12.2(33)SRB
environment.
BFD will occasionally toggle our 10G interfaces when we do "write
mem" or shut/no shut, and I'd like to verify that the problem is
caused by the routers running 12.2(18)SXF7. If so I can upgrade
all routers to 12.2(33)SRB. Otherwise I'll have to consider
running ospf fast hello.
The "shut/no shut/wr" bug is already known. CSCsc96524[1]. The bug id
status is 'terminated/closed", however it doesnt seem to be fixed.
Pretty funny that you sent this today, we were just testing SXF/SRB
BFD compatibility.
So far, the only workaround we have found is to set the BDF timers to
250ms. We're running 250ms BFD on SXF since over a year without any
issue.
As far as I remember 150ms was flapping, 200ms not, so we took 250ms
to have some margin.
If this doesnt meet your requirements, I urge you to ask cisco to
reopen this Bug since its absolutly not fixed.
Regards,
Pascal
