Ying,
Here are some notes I made a while back that might help. I originally
didn't think you could do this either, but I believe Guy Lupi and maybe
someone else sent some examples showing how to do it. You might want to
search on my name and Guy Lupi's in the archive to find the thread.
Hope this helps!
George

IPXWAN
You don't have to enable IPXWAN in order to implement NLSP. If you have
IPX RIP and NLSP both enabled IPXWAN prefers NLSP. IPXWAN will use
EIGRP. The configuration below shows how to set it up. When I tried
these out, I first had to set up EIGRP across the link and let it form
an adjacency. Once that was done it would let me add IPXWAN to the
interfaces. Until I did that I couldn't get EIGRP to form an adjacency
across the IPXWAN link for anything. The IPXWAN debug showed that it
was still negotiating RIP across the link (in the absence of NLSP) but
that routes that were exchanged across the link were indeed EIGRP
routes. The RFC for IPXWAN is RFC 1634.
To turn off rip for all networks, use no network all under the rip
config. I don't believe that no ipx router rip works, since rip is
always on by default. To get ipx ipxwan to work with eigrp, you can do
a couple of
things:
This first method uses network number 14 as the ipxwan network number.
R4
interface Serial0
ip address 14.14.14.4 255.255.255.0
no ip directed-broadcast
no ip mroute-cache
ipx ipxwan 0 14 r4
no fair-queue

r4# sh ipx eigrp neigh
IPX EIGRP Neighbors for process 100
H Address Interface Hold Uptime SRTT RTO Q Seq
                                        (sec) (ms) Cnt Num
0 14.0000.0011.0000 Se0 11 00:01:50 16 200 0 2
r4#

R1

interface Serial1
ip address 14.14.14.1 255.255.255.0
ipx ipxwan 0 14 r1
clockrate 1300000

r1#sh ipx eigrp neigh
IPX EIGRP Neighbors for process 100

r1#

This next method uses no network number, but the internal network is in
the ipx eigrp config:
R4
ipx internal-network 44

ipx router eigrp 100

Hi,

I might answer my own question. When hard code the
ipxwan network number and enter it into ipx router
eigrp, the router will accept it, but when you 'show
run', it won't be there. If you use 'show ipx int'
command to see what's negotiated, it will show up as
rip or nlsp depends what you configured in the config.
That tells me we cannot run ipx ipxwan over eigrp.

Please correct me if I'm wrong.

Thanks,
Chang
