guys i am having some probs with a config
i have two routers conected over atm and i have multi area`s configured on
this
r1 ---------r10
i have put some loopback`s on both routers
on r10 i redistributed on the first isis instance ..
and that worked ok
on r1 i redistributed on the second isis instance
what i noticed is that r10 worked ok .
r1 would not work until i put ip( router isis "steve" )on the loopback
interface`s
anyone got any idea`s why i need the ip router isis command when using the
second instance of isis even thought i am only redistributing in 1 instance
TIA
here is the config`s
