Hi,
We are having an OSPF issue. At least i'm assuming it's an OSPF issue because
there are no static routes involved.
We have our core router (imagestream) connected via Fiber to a Mikrotik at
Tower A, Which in turn is connected via 2 RB411AH's with Atheros AR922X's to a
Mikrotik at Tower B. Every 500-1000 pings we are loosing pings to 1 of the IP
addresses on a bridge interface on the Mikrotik at Tower B. When this happens
I see an IP address that is bound to one of the interfaces on our imagestream,
show up on an MTR like so...
Host Loss% Snt Last
Avg Best Wrst StDev
1. 10.192.172.1 0.0% 3642 0.7
0.4 0.4 27.1 1.0
2. x.x.99.1 0.3% 3642 0.8
0.6 0.5 36.5 1.2
3. x.x.214.74 0.0% 3642 9.7
0.7 0.6 33.4 1.3
x.x.36.209
4. x.x.214.66 0.0% 3642 8.0
10.3 0.7 75.1 9.1
x.x.99.1
5. x.x.213.1 0.2% 3642 32.7
26.1 0.8 288.3 21.3
x.x.36.209
This is how it should look:
Host Loss% Snt Last
Avg Best Wrst StDev
1. x.x.172.1 0.0% 4 0.8
0.9 0.5 1.4 0.4
2. x.x.99.1 0.0% 4 0.7
0.8 0.6 1.0 0.2
3. x.x.214.74 0.0% 4 1.2
1.1 0.7 1.7 0.4
4. x.x.214.66 0.0% 3 29.8
15.5 5.7 29.8 12.7
5. x.x.213.1 0.0% 3 15.3
14.4 13.8 15.3 0.8
Both Mikrotik's are on 6.7, running OSPF. What we can't figure out is why this
x.x.36.209 keeps showing up in the route. While this is happening, pings come
back as: TTL exceeded. Also we aren't loosing any pings to any other IP's on
the Mikrotik in question at Tower B, nor are we loosing pings to any other IP
addresses bound to that bridge interface.
The IP that we are loosing pings to is a public IP vs the others being private
and not being in the /routing ospf networks. This may or may not be relevant.
There is also no NAT involved whatsoever.
Thanks for any input anyone can provide. This is causing us REAL issues...
