  • 1.  Leaking L1 external route to L2 in ISIS protcol

    Posted 05-28-2023 23:52

    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.
