Both routers are configured with the exact same NETs. The system IDs
need to be unique.

Subject: isis adjecency problem ethernet..help
Hi All,
I am testing isis between two routers and adjecency
is not getting formed.both the routers are sending adj
packets and not getting received by each other,i ahve
checke dthe mtu size and sees to br matching, my con
diagram is like this,both the routers are in same
area.
ip reachebility between r3 and r6 ensured!!
