Hi everyone,
Since I am novice to this forum, please excuse my incompetence:-). I
have FWSM in cat6k performing central role in my network.
The FWSM is running OS 3.1.1. It has 4-5 OSFP NSSA in one ospf routing
process and one normal ospf area in a second OSPF process.
Redistribution from the first to the second routing process is done. The
strange problem appears without any clue in the log file - routes that
are in the OSPF database - more specifically OSPF IA disappear from the
routing table. After clearing the ospf process they appear again. (The
LSA are in the database all the time without expiring). Unfortunately
this is very important device, because it performs routing between MPLS
VRFs and any lost of routing information is a tragedy. The most dramatic
situation was when the FWSM lost its default gateway - all the areas
left without the default gateway and being NSSA this was near to lost of
connectivity:-)
I checked the Release notes, there is no such strange effect
described:-) . This is not a lab, so reloading and upgrading/downgrading
must be the last choice.
Any help will be appreciated,
Greetings,
Lora
