Can someone tell me whats going on here. I've got NLSP enabled between 2
routers on a token ring segments. RIP works fine, and I can IPX ping across
between the 2 routers.
R2(to0)-------(to0)R4
However, I have also enabled NLSP, but the adjacency doesn't come up.R2 sits
in the INIT state. A debug shows the following error on R2
#R2
*Mar 1 03:20:34.647: NLSP-Adj: Rec L1 IIH from 0000.30e2.6d0c (TokenRing0),
cir type L1, cir id 0000.30E2.6D0C.04 (no-mc)
*Mar 1 03:20:39.451: NLSP-Adj: Encapsulation failed for level 1 IIH on
TokenRing0
It looks like R2 receives the HELLO from R4, tries to form a packet and then
fails to encapsulate it for some reason. I know about encaps problems on
frame relay and how to get round it, but on Token ring I cant think what the
problem could be.
Just before I sent this e-mail out, I set up an internal network number on
R2 and was surprised to suddenly see the adjacency come up, with no
encapsulation failures. What has internal n/w number got to do with the
HELLO packets. I thought that the HELLO packet contained the n/w of the link
and the area address. If these 2 agree the adjacency should come up. Is this
is a bug or am I missing something. I am using IOS 12.016.
Any help would be appreciated
Thanks
