Hi Scott
we were having a lot of routers on different OSPF areas. Then due to our
topology I thought it was better and much more stable to work with other
stragegies.
Yes we had some memory issues (leaks?) with flapping but obviously the
solution is not on the OSPF side but on the link part of the
infrastrucutre (to avoid flapping)
I am glad it worked for you, but it is not working for us :)
Thank you for the feedback
Paolo
Please define "many routers." We have over 600 RouterBoards
participating in OSPF and the only time we have an issue is when a
wireless link flaps as OSPF needs to recalculate the table before it is
done. That seems to be where there is a memory issue.

yes STILL....OSPF has issues when your network has many routers
participating to the OSPF graph. The simple solution is to decrease
teh number or routers in the graph i.e. do not use OSPF where not
absolutely needed and use static routing where possible
Also you have to use the right 'configuration' on the link (if you are
using wireless to connect) in order to let the OSPF messages pass.
Usually ptpm solve many link issues
Occasionally, I see OSPF disappearing or not properly working in some
links, i.e. traffic passing but OSPF down on that link. In that case,
rebooting the LINK (not the router) makes things go again
Obviously this opens some problems when you are using PPPoE or
accordingly with your network infrastructure.

All-
I've been noticing a lot of OSPF/route issues, mostly with older
code as I've been adjusting the network (properly). After some
network maintenance I'm going to be bought some time, but I've lost
connections to routers (where rebooting brought them right back, no
changes). Travelling to a router at whenever, not fun, and I know
it's my fault because I don't have OOB built yet.
It looks like this:

Does anyone have a CR# for this so we can confirm OSPF fixes, or
perhaps a recommended Code to run until it is?
It looks like some of yall are seeing the same thing.
What's the best code for OSPF/routes?
