Re: import routes from one NSSA Are in another NSSA Area

hi thanks for your respond,

I think the main requirement might because of you are asked to do it sense
or non-sense doesn't matter :)

I labbed it up and i could get it working with tunnels but i could not get
it working as summary or area range if you get this I would be interested in
the config for that. ;)

thanks for your effort.

cheers Reni
