Yes, I think ISIS will not work on multipoint interfaces. You have use point
to point.

I beleive you have two options,
1.) add "frame-relay map clns" commands (never tried, but heard it works)
2.) you point-to-point sub interfaces.
I hope this helps, let me know if you have any luck with #1
Cheers,
Robert

Hi all,
I am having an issue with getting ISIS operational in the lab. Between
router 14 and router 5 over a frame link we are supposed to run ISIS type 1.
I have the link up frame map shows good and can ping the line. I configure
bother routers with the command "router isis" use a net number of
49.0001.7777.7777.7777.00 on 14 and 49.0001.5555.5555.5555.00 on router 5. I
then configure the interface with "ip router isis" on the appropriate
interfaces and loopbacks. No luck no isis routes in my routing table. I then
added type 1 and 2 support to the config no luck. So I do a debug isis adj
on r 14 and see it is sending a request for adj but does not get a reply. So
I go to r5 and do the same and now I see something much worse.
02:49:47: ISIS-Adj: rcvd state DOWN, old state INIT, new state INIT
02:49:47: ISIS-Adj: Action = GOING UP, new type = L1L2
02:49:48: ISIS-Adj: Encapsulation failed for level 1 IIH on Serial0/0
02:49:50: ISIS-Adj: Encapsulation failed for level 2 IIH on Serial0/0
02:49:50: ISIS-Adj: Encapsulation failed for level 1 IIH on Serial0/0
02:49:52: ISIS-Adj: Sending L1 IIH on Loopback0
02:49:53: ISIS-Adj: Encapsulation failed for level 2 IIH on Serial0/0
02:49:53: ISIS-Adj: Encapsulation failed for level 1 IIH on Serial0/0
02:49:54: ISIS-Adj: Sending L2 IIH on Loopback0
02:49:56: ISIS-Adj: Encapsulation failed for level 2 IIH on Serial0/0
02:49:56: ISIS-Adj: Rec serial IIH from DLCI 105 (Serial0/0), cir type L1L2,
cir
id 00
My router is having encapsulation failures and the link is flapping but only
for ISIS. I enable eigrp on the link on both ends and viola it works fine
but still no ISIS.
Please look at the configs and see if you can spot the issue???
