Tcpdump is clearly one of my favorite tool. Here a little example to filter the traffic of my OSPF router.
tcpdump -i eth0 ip[9] == 89
And the result:
12:43:48.219432 IP p2b.soif.fr > OSPF-ALL.MCAST.NET: OSPFv2, Hello (1), length: 48
12:43:48.560817 IP wrt.soif.fr > OSPF-ALL.MCAST.NET: OSPFv2, Hello (1), length: 48
Wonderfull no ? :)
