You can't just do an IMA on any T1 controllers, you'll need IMA cards. check links out: http://www.cisco.com/univercd/cc/td/doc/pcat/enatt1a1.htm The following benefits are offered by the ATM T1/E1 IMA features for the Cisco 2600 and 3600 series routers: High-bandwidth performance at a lower cost than T3 and E3 Internetworking design flexibility and scalability for LAN-to-WAN solutions Migration path to high bandwidth without the need to change transport facilities Efficient prioritization provided by the ATM architecture Check this link too: http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120t/120t5/atm_ima.htm#xtocid99554 >From: "tcb" >Reply-To: "tcb" >To: [EMAIL PROTECTED] >Subject: Weird Scenario question [7:7590] >Date: Thu, 7 Jun 2001 15:06:00 -0400 > >************ > * * > Router1 * RTR * > * * > ************ > | | | | | | > | | | | | | > T-1 Lines -------> | | | | | | > | | | | | | > / / / \ \ \ > / / / \ \ \ > ****** ****** > * * * * > Router2 * RTR* * RTR* Router3 > * * * * > ****** ****** > >Ok I currently have 2 routers going to core router up above.
