management of network ports

[dmalamba]

I have a cisco 2611 router which i want to use both of its ethernet ports to be conected to same LAN i.e switch. The moment i configure the ports to be in the same network i.e having similar ip addresses e.g 192.168.100.207 and 192.168.100.208 i am receiving an error that there is an overlap. What do i do to resolve this. What if i connect another router to the same switch would their be a conflict as well. I want to do that inorder that i reduce load on one ethernet port which is my gate way to about 16 remote sites and the internet

you cannot set two layer3 ports in one subnet, except using bridge. if u use another router,its ok.

if you want reduce load, i think the bottleneck is not on ethernet port, but the cpu. the forward rate of 2611 is just <20kpps.

hi,

on any router u cant put 2 ports in same subnet, whether you use 2611 or any other router.

u can try making etherchannel between router and switch, if it is supported on your router.This way you can load balance the links.

Did you ever find a solution to this problem? I want to do something very similar - I have cisco 3600/3700 series routers which have dual ethernet ports - I want to have both connected to separate blades in the same switch, so I have redundant connections. I've heard that the 3745 will support etherchannel on the interfaces, but I've been at it a few hours now and haven't been able to make this work. Another thought I had was to run EIGRP on the inside, and use it to load balance between both links to a loopback address - haven't fully tested this yet. I don't see why a 2611 couldn't use both ethernets on the same subnet - EIGRP should facililtage for load balancing across the links. I haven't tested this though on that platform.
