Hi,
We have two routerss connected by wan links and OSPF is enabled on this interfaces. On each router we have Channelised E1 controller to which 30 locations are connected. We are using static routes to in these two routers to route the data to these 30 locations. Secondly we are having ISDN-PRI configuration as a backup for these static links. for example
ip route Network_A serial 1/1:0
ip route Network_A dialer 0 200
This is how we are routing traffic when serial link goes gown.
In ospf process follwoing commands are given
redistribute static sunbets
redistribute connected subnets.
It works correct for all serial links. All serial routes are redistributed to other routers in the OSPF process. Problem comes when one location goes on ISDN backup line. On that router we can see that location is connected on isdn ,I can even ping to that location router ethernet. But this route of cost 200 is not redistributed in the OSPF process. When i removed the secondary command of 200 and again put it back , then it immediately redistributes this route in the network. And we get the connectivity to that location from the rest of the network. ( If I check with
show ip route Network_A command , it shows subnet on in the table. )
Why this is happening how can we rectify it.
Thanks in advance !
