Hi there,
I'm now playing with IS-IS routing for IP in my lab (attempting to replace
an OSPF configuration).
The links are a mixture of ethernet and serial (Frame Relay).
I have no problems with ethernet links, F/R physical or point-to-point
links, but I do not seem to be able to get a link between a F/R
point-to-point link on one router to form an adjacency with an F/R
multipoint link on another router.
On the point-to-point link, the adjacency appears to form (show clns neigh
displays the remote router as being Up), but on the multipoint router the
clns neigh seems to stay in Init state.
I cannot find anything talking about F/R issues in the Cisco documentation,
and just want to check that I'm not attempting to flog a dead horse here.
Should this configuration work ?

Derek...
