I can confirm, the server that was "working fine" also crashes if I configure an ibgp session. It looks like some bgp operations are tricky to radix_mpath. I noticed some people saying ecmp is trivial and stable on OpenBSD, did someone test this? I really need this feature and the time is short. I'm considering migrate all routers to OpenBSD, Thanks in advance --=20 Andr=E9 Gustavo N.
