Hi,
I have the been going through ISIS in the LAB mainly from Doyles, Routing
TCP/IP Vol 1 (pg668-671)
I'm having the following problems getting authentication working in the
following set-up.
L1 L1/L2
[Wacky52]-----------[Noddy]------->(L2 Router)
11.2(24) 12.0(7)T
Noddy is in the same area as Wackey and they have established a L1
adjacency. When I set-up an "area-password cisco" within Wackey and "clear
isis *" both routers then establish an L1 adjacency?? This doesn't seem
right.
As an alternative I set up L1 ISIS password on the serial of Wacky52 but not
Noddy and it still works, if I change the password to be a L2 adj. fails.
Can anyone offer any guidance? (I have the password set-up on one router
and not the other, hence authentication should fail, when the pwd type is L1
as its a L1 connection.)
Thanks,
Philip.
