After some restarts of ospfd - nearly all works fine. All - but no one
tunnel - between RA1 and RB2. Unfortunly - RA1 is in production state, so i
can't restart it :-)
Does anybody have any idea how to debug/fix problem without restarting
quagga on RA1?
I've put some commands from routers for comparision to
MTU is 1500, pings of size 1500bytes works fine - so i think that it's not
a problem with MTU.
config for interface in quagga on both sides is:
ip ospf network point-to-point
ipv6 nd suppress-ra
