2651 router w/ CEF

[georgeburtz]

I have an internet facing router (2651) with a single T1 to the provider. I want to add a second T1 and bond them together. The provider doesn't do multilink PPP, they use CEF to load balance over the 2 circuits. This router is maxed out on DRAM and runs BGP for external routes. CPU load averages about 20% steady.

Question - If I add this circuit and run CEF, will this router be able to handle this? Should I upgrade to a 37xx?

Thanks!!

Hello,

this should be no problem for the 2651, in fact, turning on CEF reduces the CPU utilization considerably, as less packets are process switched and more packets are fast switched.

HTH,
