What about IP Classless... is "no ip classless" part of the current config... if so, try removing it.
also, auto-summary might be something to look at... if you don't see it in the config, try a "no auto-summary" under the eigrp 100 config. you should also turn on some debugging, and log it to a syslog server of sorts to get a more precise idea as to what is causing the interface change.

This is connected to two different sites with 64kbps links. eg interface serial 0/0 ip address 192.168.1.1 255.255.255.252 interface serial 0/1 ip address 192.168.1.5 255.255.255.252 router is running with routing protocol EIGRP router eigrp 100 network 192.168.1.0 Problem: I'm able to work with only ONE serial link at a time. ie. If one serial link is active, other one becomes "line protocol down" If I remove the cable of the UP interface, the OTHER interface become UP I suspect this is due to the operation of EIGRP Because I cannot configure subnet mask for the network defined under eigrp 100 This particular IOS doesn't allow me to do this and DRAM and FLASH limitation prevents me from upgrading the IOS. Can any one tell me how to overcome the situation? Thanks, Vajira 12.0.8 ip ----------------------------------------- (on postoffice) The information contained in this email is confidential and is meant to be read only by the person to whom it is addressed.Please visit http://www.millenniumit.com/legal/email.htm to read the entire confidentiality clause. --------------------------------------------------------- Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=33642&t=33636 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
