R2:
interface Serial0.4 multipoint
ip address 136.10.24.2 255.255.255.248
ip router isis
R4:
interface Serial0
ip address 136.10.24.4 255.255.255.248
ip router isis
You have a network type mismatch problem. In your configuration, one
side is multipoint and the other side uses the physical interface. Take
a look at "debug isis adj-packets" and "sh clns neighbors" on each side.
Search the archives and you will find a lot of discussion on the
subject. Take a look at the new "isis network point-to-point" command.
I like Kym Blair's post:
