Hello Navaid,
i spent some time with this one...
here is my solution for a specific case.
but it will give you the idea ....
r1---se0-r2-se1---r3
r1-r2 are L2 neighbors...
r2-r3 ara L2 neighbors...
Description:
what i do is, create another isis process on r2,
with the same area id of r3 (enable it on se 1)
so that it will receive r3 routes as Level-1.
and another process on r1,
enable it on se 0,
so that it will be a L2 nei of r1 over se0
and use
redistribute isis ip level-1 into level-2 distribute-list 100
to filter the routes...
how to filter r3 routers so that r1 does not receive it...on r2
r3
------------------------
router isis
net 49.0003.0000.0000.0003.00
passive-int lo 0
passive-int lo 1
..
r2
-----------------------
int se 0
ip router isis
int se 1
ip router isis 2
router isis
net 49.0002.0000.0000.0002.00
redistribute isis ip level-1 into level-2 distribute-list 100
!
router isis 2
net 49.0003.0000.0000.0002.00
is-type level-1
access-l 100 permit ip host [route1] any
access-l 100 permit ip host [route2] any
....
r1
---- router isis net 49.0001.0000.0000.0002.00another thing is u can use distance 255 to filter every route... this is not what u want probably...

How do we filter routers so neighbor do not see our routes.... I am unable to find distribute-list under router isis.
