MI ha a important problem . I lost conectivy . My situation is as follows:
I have a Central router 7200 which collects 600 remote routers. He reduced to half from (20 to 10 sg) rip the time of updates.
Old tiemrs: 20 40 40 40
Current timers: 10 20 20 20
The effect is that the remote left to learn the routes which distributes the central . The only sends it that this is the default route that learns via OSPF. Thiscentral is the ASBR of one NSSA. It is possible that is losting defCte default route by learnt by ospf and then redistributed by rip to remote routers by some sort of bug.
