Please could you explain me the following:
we have such topology
R1 - R2 -R3 -BB1
R1-R2-R3 is connected with ethernet
R3-BB1 is connected with ATM
R1 - int area 1
r2,r3,BB1 in isis area 2
R1 - R2 - level-2 only connection
R2-R3 level 1 conn
R3-BB1 level 1 connection
1.R3 see the default isis connection to R2. So it can access all external
routers in outside router R1. (As normally in the stub network).
BB1 doesn't have this default route. Why?? It have only L1 routes in it's
area and nothing about how to reach the outside routers. I thought that L1
routers should pass the information between each other.
Any idia??
When redistributin for example Ospf into isis level1 on R2 router I also had
the problem that R3 gets some routes which BB1 doesn't.
I totally don't understand why.
Please help....
