Hi Misc@,
Right now i'm playin' with bgpd filter setup. I've successfully create an
ebgp between another obsd4.3-current and ibgp between a fbsd/zebra.
I understand on most ibgp implementation (ciscoz/quagga), prefixes from
ebgp peer are more preferred than ibgp. But that isn't happening here.
Say,
|----------------------quagga/linux---------------------------------|
| as65020 |
| |
| |----ebgp---|----4.3current----|-----ebgp----|
| | | | as65024 | |
fbsd/zebra ----ibgp--- 4.3-current carp1 ibgp carp0 |
as65021 | as65021 | | | |
|----ebgp---|----4.3current----|-----ebgp----|
as65024
fbsd/zebra as65021 have the same peer/prefix feeder(as65020) as
as65024/4.3-current. But 4.3current/as65021 prefer prefixes from
fbsd/zebra as the paths are sorter, I think..
So I create a filter:
deny from {IP_address_fbsd/zebra} AS 65020
But it still receive valid prefixes from fbsd/zebra. I appriciate if
someone could help me/hints me on howto prefer prefixes from
as65024(ebgp-peers) than ibgp peers without changing the setting on
fbsd/zebra.
Thanks,
