[j-nsp] ISIS route leaking from Level2 to Level1

[Cydon Satyr]

Hello experts,

If I create an aggregate route on L1/2 router and export it to Level1 ("to
level 1"), this route does not have up/down bit set, making it eligible for
leaking back to Level 2.
What happens is that now router which originated aggregated route prefers
same route over ISIS making a constant oscillation.

Is there a way to prevent this?


Thanks
