Aggregate 4 T1s w/ Cisco Express Forwarding

I need to connect Site A (HQ) to Site B (DataCenter). Bandwidth requirements are 6Mbps. Sites A and B are across the street from each other. What is the best way to load balance 4 point-to-point t1 leased lines between 2 3640s. CEF? If so, could anyone provide a sample config?

Hello,

I would put the 4 T1 leased lines in a ppp multilink bundle. To configure this, put the following commands on each interface you want to have in the multilink bundle:

ppp multilink

multilink-group 1

By the way, as far as I know, CEF defines the fastest method by which a Cisco router forwards packets from ingress to egress interfaces, so it only applies to switching packets within the router, not between routers.

Regards,

Georg

CEF should work fine for this, as well. MLPPP will suck up more processing power, but will probably share the load more closely.
