Also Bob,
With IPX, you don't need to worry about putting networks on loopbacks. Think
about it, IPX is a desktop protocol for connecting LANs. I've never had a
problem with using the 'ipx routing 1.1.1' convention.
Regards,
Daniel

Bob,
You're defining a multicast address. This is from
http://www.cisco.com/warp/customer/473/85.shtml#multicast :
Note: Recall that the least significant bit of the most significant octet of
an Ethernet or FDDI MAC address is the "group bit." If the bit is set (1),
the MAC address is a
multicast (or broadcast). If the bit is not set (0), the MAC address is a
unicast. The MAC address 0900.3333.4444 has the group bit set, and is
therefore a multicast
MAC (09 hex = 00001001; the last bit, the group bit, is set).

Subject: ipx routing 1111.1111.1111
When I configure a router with
ipx routing 1111.1111.1111
and then configure a loopback
int lo0
ipx netw 10
if I do a show ipx int lo0 the ipx address is 10.1111.1111.1111
if I then ping this address from the same router (i.e the router on which
this is configured) my pings timeout.
If I do not configure an address with the ipx routing command the ipx add of
the lo0
uses tha mac address of the ethernet interface on the router and when I now
ping the lo0 it works
p 10.0010.7bfe.6cc1
Translating "10.0010.7bfe.6cc1"
Type escape sequence to abort.
Sending 5, 100-byte IPX cisco Echoes to 10.0010.7bfe.6cc1, timeout is 2
seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms
Can anyone explain why this happens. I was thinking of configuring my ipx
routers like the first method above as it makes configuring frame-relay
maps easier to configure and troubleshoot but the side-effect is what I just
described.
Thanks
Bob
