[8.280][NOTABUG][CLOSED] OSPF is flapping

The route are shown on both sides. Two router with one area. Connected through a RED tunnel.

But they are thrown away after a few seconds. I see the route within the routingtable as zebra routes, but they are not working. What am I doing wrong?

There are even OSPF Packets dropped:


01:08:18 	Default DROP 	2  192.168.98.2 	  	 	→ 	224.0.0.22 	  	 len=48 	ttl=1 	tos=0x00 	srcmac=

01:08:18 	Default DROP 	89 	192.168.98.2 	  	 → 	224.0.0.5

Hi mayguyver,

i suspect that there are some packet filter rules missing. can you please post the output of 'iptables -nvL AUTO_OUTPUT'?

Thanks

Hi

I think you want to see this rules, but they are not working. Seems the traffic is not generated by reds3.

0 0 CONFIRMED 2 -- * reds3 0.0.0.0/0 224.0.0.22
0 0 CONFIRMED 89 -- * reds3 0.0.0.0/0 0.0.0.0/0

I traced, on reds3. There are a lot of OSPF packets. But the OSPF routes are not working.

Problems seems to be the ASG to ASG RED tunnel.

When I am activating OSPF the Tunnel is dropped.

Hmm, what routes are you redistributing in your OSPF setup? is it possible that they are disturbing the RED control connection?

I distribute all link connections.

Yes, within the distrubution is although the RED target IP.

But how do I fix that? I am not able to skip one interface from ditributing.
(May be a static route for the RED target IP?) Yes it is working.

Thanks I had been blind after checking so much stuff.
