Subject: Re: bri flapping with demand cirquit/igrp

Redistribution brings it up.
What happens is, the link is brought up and OSPF
forms an adjacency. Then,
since it is a demand circuit, periodic LSA's are
squelched and OSPF routes
associated with those LSA's do not age out of the
routing table. Then, the
layer 2 portion of the link drops, since there is
no interesting traffic.
Once the link drops, whatever protocol you are
redistributing into OSPF sees
it's link drop, and changes its tables in
accordance with the topology
change. This change gets redistributed into OSPF,
and OSPF floods LSA's out
announcing the change. These LSA's bring up the
link while OSPF converges.
Then, after a while, things are stable again, and
the link drops - and guess
what? That's right! The whole thing starts
again...
There are ways to stop it.

I also had the same problem a few days ago. Here
is how I fixed it:
1. Isolate the problem by shutting down all
other interfaces besides the
interfaces
between the two related routers;
2. Disable all other routing protocols (non-OSPF
ones);
3. Turn off IGRP redistribution to OSPF;
3. Now, verify the ISDN demand circuit. It
should be quiet now.
4. Now, start unshut the interfaces you have shut
down one by one and
verify
that the ISDN demand circuit. It should
might come up briefly but it
should go
down and keep quiet after some interfaces
are unshut. If the ISDN
line
keep dialing, you should know which interface
is causing the problem.
5. If the ISDN line is still quiet after you
unshut all interfaces, turn on
your other router
protocols such as IGRN, RIP, etc one by one.
Again, verify the IDN
line after
each change as above.
5. If the ISDN line is still quiet after you
enable all other routing
protocols, turn on your
redistribution one by one. Again verify ISDN
line along the way.
If you follow these steps, you should be able to
pin down what is causing
your ISDN
line to stay up.
Hope it helps.

CDP may work at layer 2 but if the line is
brought up because of web
traffic
CDP packets would then traverse the line
consume a small amount of
bandwidth.
I have installed a few ISDN DDR VPN's without

the whole idea for DDR is that only interesting traffic will bring up the link. Once the link is active, then by all means, the routing protocols can send hello messages.

Re: bri flapping with demand cirquit/igrp redistribution
Redistribution brings it up. What happens is, the link is brought up and OSPF forms an adjacency. Then, since it is a demand circuit, periodic LSA's are squelched and OSPF routes associated with those LSA's do not age out of the routing table. Then, the layer 2 portion of the link drops, since there is no interesting traffic. Once the link drops, whatever protocol you are redistributing into OSPF sees it's link drop, and changes its tables in accordance with the topology change. This change gets redistributed into OSPF, and OSPF floods LSA's out announcing the change. These LSA's bring up the link while OSPF converges. Then, after a while, things are stable again, and the link drops - and guess what? That's right! The whole thing starts again... There are ways to stop it.

On your access list 15 try changing the mask to .255 instead of .3, even though you
