Routes across ISIS areas. [7:61433]

2003-01-20 Thread Rajesh Kumar
Hi all,

I have a scenario like this :

Area 1 Area 2

R1  R2

s2/0.1 s2/0.1

Both are point to point networks.

The configuration for R1 is

int s2/0.1 point-to-point
ip router isis

router isis
net 47.0001.0002.0003.0004.00

and for R2 is

int s2/0.1 point-to-point
ip router isis

router isis
net 47.0002.0001.0003.0004.00


=

The problem is that I am not able to see R1's routes in R2.

R1 has a couple of OSPF routes coming in from other routers - but never
gets passed on to R2.

Any experts comments?


Thanks,
Rajesh

Rajesh,

 47.0001 will not form an adjacency with 47.0002.  For them to exchange L1
 routes you need to change their ISIS Area IDs in their NET so they're in
the
 same area.  Alternatively you could insert a third router as an L2, and
leak
 your routes from the L2 into the L1s.

 You'll also need to redistribute those OSPF routes into ISIS if you want
 them announced to R2...

 HTH,

 John
