You may also want to try setting one as a DIS since the frame network is
multipoint (Similair to a DR in OSPF)
isis priority < priority>
default is 64
this is an interface config command, just like ospf priority

Hi,
Actually I got this from the IE workbook, according to the author's
(Brian's) the Net size should be same on all the routers and not
necessarily start with a 49.
Also as you can see from the output below the clns adjacenciea are
forming fine.
The only other thing I can see is this frame-realy debug-

This is happening like crazy on all the three routers, so I even removed
the isis hello statemnets thinking that maybe that was causing the
packets to be delayed.
But doesn't work either way :(
Thanks,
Mohit.

make your AFI in the NSAP the same...typically it is 47 or 49
ie..i changed the AFI in your config below
you may wany to make the system id 6 bytes
typically i use
AFI Area -------System ID--------- N Selector
XX. XXXX. XXXX. XXXX. XXXX. XX
first 2 X's are AFI.
next 4 is for area id
next 12 are system id - must be unique to each system - last 2 are N
selector..I typically leave these at 00
here is how I usually do a net for ISIS
int s0
ip add 10.10.50.2 255.255.255.0
ip router isis
router isis
net 49.0001.0100.1005.0002.00
I typically transfor the IP address to equal 6 bytes ex -
10.10.10.50.2 = 010 010 050 002 = 0100.1005.0002 for a system id :-)
HTH!
