hmm, afi 1 is IPv4, safi 4 is MPLS (not MPLSVPN!), and we don't handle that indeed. but that's not fatal. > Jun 6 13:47:54 openbsd5132 bgpd[15940]: neighbor x.x.x.x (AS 65002 peer 1): > bad VPNv4 withdraw prefix and that is fatal as in the session is dropped by sending a notification, as the next line also sez. that in turn means either prefixlen is > 32 or rde_update_get_vpn4 failed. Which in turn means either one of the validity checks or rde_update_extract_prefix failed, and rde_update_extract_prefix again only fails on a validty check. guess we need to see that update. > Jun 6 13:47:54 openbsd5132 bgpd[15919]: neighbor x.x.x.x (AS 65002 peer 1): > sending notification: error in UPDATE message, optional attribute error > > And I have tried with the gdb debugging options explained in a previous thread > but it looks like I am only able to get it to work when bgpd core dumps.
