Re: ISIS level-2 into level-1 redistribution + filtering

Hi Service provider,

If i understand correctly, you are not able to see the routes from R1 and R2
on R4 with this configuration on R3?

Is this is the problem you are missing the "route-map CLNS permit 20" in the
route-map.

Thanks
Satinder
