IS-IS help (no default route)

[fernando]

try to use this command : set protocols isis set-attached-bit in l1l2 .

although , part of this scenery can be affected with this problem :

IS-IS no network migration from level-1 to level-2 database

it seems this feature doesn’t work on FRR , at least , l1/l2 are not able to redistribute L1 into L2 which is expected beheivor : I’ll create a task in our vyos.dev to document it , if you can make a comment confirming it on FRR 9 , it would be great .
