[c-nsp] ISIS set-attached-bit route-map

[selamat pagi]

Hi,

In my lab setup I have 3 routers connected via IS-IS
R4 --(frame-relay)  R5 --(ethernet) - R6

On R5 I have to areas,  connected, however  I only want to
originate the default-route to R6 when R4 is reachable.
I tried to use a the set-attached-bit route-map with clns filter-set, but I
cannot control the default route as desired.

Any idea how this can be solved ?

thanks, ketimun

route-map REAL_L2 permit 10
 match clns address R4

clns filter-set R4 permit 49.4444   --> * This route is not int the clns
