bonding T1's

[dave-oconnor]

what is the best and cheapest to bond 2 t1's into one 3m point to point pipe?, would it be better to do it internally in the router or using a mux, and what would be the smallest router that could handle this task?

[deilert]

what you can do is use ppp multilink

Another note, the most important traffic on the link is going to be multicast traffic, it will mostly be below 1.5 meg, but at times it will shoot up above that, up to at least 2 meg. the most important factor is the speed, this data cannot be delayed for any reason, I'm dreaming right?, anyway thanks in advance.

Speed is going to be based on distance and the amount of traffic you are sending through the pipe the further the distance the longer the delay, coast to coast is approx 70 Ms round trip

PPP Multilink or CEF per-packet load balancing. Try them both and see which one works better in your scenario.

so would a 3600 handle this okay? also one more small question, we are hoping to have a hub and spoke topology with a big enterprise router going to several locations is there any suggestions about configuration for this central location?

[t.baranski]

A 3600 can handle 2Mbits easy.

Hub and spoke designs can be configured any number of ways. A lot of times, each site has a Frame Relay PVC back to HQ. All the PVCs are aggregated onto a single circuit (e.g., a T1 or T3 depending on the number of sites and bandwidth of the PVCs). Separate point-to-point links per site are also an option, though a more expensive one relative to Frame Relay.

If you Google around for "hub and spoke" you should be able to find some good examples.
