Hi. I'm trying to get rid of quagga on most of my routers. When they run BGP/OSPF everything is fine, but when it comes to RIP, bird crashes. I run bird on a set of VPN tunnels, mostly gre. I need RIP because Cisco marketoids keep on manufacturing small boxes that cannot run OSPF, only RIP is available. Bird crashes as soon as the protocol exchange is started. Here's a backtrace along with some info about the setup: ===Cut=== [emz@moscow-alpha:~/bird.cores]# gdb /usr/local/sbin/bird bird.core GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
