packet hello received problem
|
|
Hi,
I have problem between two routers with protocol ospf.
1. Linux debian with quagga (0.99.20.1-0)
2. Mikrotik system
Quagga sent hello packet to multicast but not received hello packet from second router
(debug-quagga)
2012/06/10 21:33:57 OSPF: Hello sent to [224.0.0.5] via [vlan203:10.10.11.1].
2012/06/10 21:34:07 OSPF: Hello sent to [224.0.0.5] via [vlan203:10.10.11.1].
2012/06/10 21:34:17 OSPF: Hello sent to [224.0.0.5] via [vlan203:10.10.11.1].
2012/06/10 21:34:27 OSPF: Hello sent to [224.0.0.5] via [vlan203:10.10.11.1].
And you see, "packet hello" was sent but not see received from second router.
But when I look tcpdump on interface vlan203 I see second router sent "packet hello"
Sometimes quagga loged that "packet hello" received and sessions is established, but not always.
root [at] cerbe:~# tcpdump -i vlan203 ip[9] == 89 -n
