Jason nailed it. I put a crossover cable between R5 and R6 and the
adjacency formed. I don't know what the switch is doing to stop the
multicasts. I setup eigrp and ospf using that switch which also use
multicasts and those work fine. Those are IP to Ethernet multicasts while
ISIS uses CLNS to Ethernet multicasts, I don't know if that makes a
difference.

Subject: ISIS over Ethernet
I can't get ISIS adjacencies to form over ethernet. Connectivity and config
are at the end. I have tried several different NET addresses from with the
doccd or the Doyle book. All three routers will form ajacencies over serial
and R4 has a token interface it will form an adjacency over. If I give the
CLNS Enable command on the ether interfaces they will form an ES-IS
adjacency. When doing debug ISIS adj-events every router says it is
transmitting L1 and L2 IIH packets, but no of the routers see any hellos
coming in. The interfaces are up/up, ping and cdp are working over these
links.
The problem boils down to all router say they are transmitting hellos but no
of the routers say they are recieving hellos.

ip router isis
router isis
