First, thanks for all the information. I forgot to mention that when I did a Show ip int brief I saw up and up. Next, here is some pertinent configuration information:
Interface Serial 2/5 mtu 2044 ip address 172.25.x.x 255.255.255.252 encapsulation ppp ipx network B051 ipx update interval rip 300 ipx update interval sap 300 nrzi-encoding router ospf 200 log-adjacency-changes network 172.25.0.0 0.0.255.255 area 0.0.0.0 Sh ver is as follows: Version 12.0(7)XE1 IBM 6611 cisco 7204VXR (NPE225) processor with 122880K/8192K bytes of memory. R527x CPU at 262Mhz, Implementation 40, Rev 10.0, 2048KB L2 Cache 4 slot VXR midplane, Version 2.3 This router was exchanging OSPF updates with a Cisco 1601 via a different serial interface. I was also using PPP encapsulation on both interfaces there and it worked fine. Finally, I have to say that we have this configuration in another location with five serial ports connected to various IBM routers via T-1. All of the serial ports have identical configurations as the serial port listed above. Unfortunately, we are on a live network here and I cannot plug this router back into the network to look at logs. I would have to take down a courthouse and that has to be scheduled far in advance. Plus, they would not like it if I took them down to do 'testing'! Thanks again for the information and keep it coming!
