Hi everyone.Is there anyway can we tell L1/L2 router to take L1 external route and announce into L2 without using wide metric and policy?Much appreciated!!
You have to do route leaking using a routing policy. In the policy, you would use the conditions from level 1 and to level 2 in addition to other conditions like from protocol isis and also perhaps a route-filter. The policy gets applied as an export to IS-IS.
Appreciated !!That is what I thinking as well .
