That's not really a router ID that you're assigning. It's a node address to use on a serial link. Are you running IPX on one of your serial links? An IPX address consists of network.node. IPX uses the MAC address for the node part. That works fine on Ethernet, Token Ring, and FDDI. Each such interface has a MAC address. So when a router sends RIP or SAP or other router-sourced packets out an Ethernet interface, for example, the network-layer IPX addresss might be something like it is on my router, consisting of the network number I assigned, followed by the burned-in MAC address: Boston#show ipx int e0 Ethernet0 is up, line protocol is up IPX address is 500.0000.0c02.74c7 But a serial interface doesn't have a MAC address! So what it should use? By default it uses the MAC address of the first Ethernet, Token Ring ,or FDDI interface. If none of those exist, then it makes one up based on the system clock. If you don't want it to do that for some weird reason, than you can tell it the MAC address to use on serial interfaces by configuring a parameter with the ipx routing command. Boston(config)#ipx routing 2.2.2 Boston(config)#end Notice that it worked on my router: Boston#show ipx int s0 Serial0 is up, line protocol is up IPX address is 400.0002.0002.0002 [up] Although e0 hasn't changed: Boston#show ipx int e0 Ethernet0 is up, line protocol is up IPX address is 500.0000.0c02.74c7 The change does show up in show run on my router: Boston#show run Building configuration...

So why would you be seeing something different is the REAL question. ;-) Are you sure you are actually running IPX on a serial interface? Do you have a serial interface? Are you sure you typed in 2.2.2 correctly? Do they make you do 0002.0002.0002 in newer versions?? Are you running DECnet which changes MAC addresses? Could they have changed the behavior in 12.1(5)T? Someone else would have to check that. I can't afford new routers. ;-) _______________________________ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com >Problem is after I > type this address and show run the router has taken one of the > interface's Mac addresses as the router IPX ID.
