1. How about "passive-interface"?
 
2. Participating at Level-1 in two different areas - useful for MPLS TE
perhaps. Or a way to handle mergers.

3. If memory serves, "debug isis rib local"

Hi,

i have few basic questions about isis,

1)Lets suppose i have two routers

R1-------Serial------R2

Link between R1 and R2 and is-type level-1 Loopbacks of both the routers are
level-2.

What can be different possiblities of getting R1 looback in R2?

1) redistribution
2)default-information-originate

what else?

2)what are the advantages of defing two NET statements on a single router?

3)If i am defing a route-tag to an isis route to increase its priority, how
can i check the high priority was given to the route?Which show command?

for example,

int ser1/1
isis tag 50
ip router isis

router isis
net 49.0001.0000.0000.0001.00
ip route priority high tag 50

How to verify it?

Thanks

BB
