Hi. Rich, At least, I'm watching this report and trying to find a
clue what causes this route flapping. I recently added a couple
of BGP4+ connections to peek more data. (Merit announces its
prefix only to most of them not to contribute to the flapping.)
There could have been configuration errors and link outages, but
I'd like to make sure that there are no other problems like an
inappropriate BGP4+ implementation before a strong route
filtering and route dampening will be introduced.
If your site would like to be investigated directly :-) or if you
are running your original BGP4+ implementation, please let me
know. I'd like to add a few more BGP4+ connections with
non-cisco routers to find a clue and keep watching our 6bone
routing.
Thanks,
Masaki
