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

Hi All

What I want to achieve is for R4 to only receive routes from R2 (49.0002)
and R3 (49.0034). I want to filter out routes from R1 (49.0001) when I
redistribute L2 routes into L1 on R3, which is L1L2 router. R4 is in the
same area as R3.

Thank you.
