Re: problem in isis route leaking

What is the output of show ip route on the router on the other side which can't see leaked routes. Can you try the below config and see if its working or not:

int lo0
 isis tag 110

router isis
 net 49.0001.0001.0001.0001.00
 redistribute isis ip level-1 into level-2 route-map match-tag

route-map match-tag permit 10
 match tag 110
