Re: How to Multiplex 3 T1s [7:4625]
I didn't see my original reply come through. How about using multilink-group # under the interfaces to bind them to a multilink interface? Example: int multilink1 ip address ... encaps ppp ppp multilink ... int s1 multilink-group 1 int s2 multilink-group 1 int s3 multilink-group 1 As for PVCs and Frame Relay, haven't tried the above method. But have done PPP over Frame Relay and combined multiple PPP over Frame circuits into 1 multilink virtual template. It worked but I did it in lab just to see if it could be done. multilink-group doesn't work on DDR interfaces, this was 12.1(5)T when the feature was introduced. It may have changed since. --- Kelly D Griffin wrote: Has anyone done this successfully and shown an increase in bandwidth? Has anyone done this with PVCs on the same router and frame port?

I am doing this right now with our frame provider. We will be using 2 for now but up to 8 t1s. We have to use the inverse mux on each side of the line (ours and the providers). With 2 T1s we just get a 3 meg frame port and off we go. We are using Quick Eagle DL3800 8 port inverse muxs.

Re: How to Multiplex 3 T1s [7:4625]
I've seen it done with 2 frame relay T1's at the hub of a hub-and-spoke topology. (There were actually 3 hub routers and 6 T1's, 1 pair IMUXed into each hub router). The router interface was a HSSI port. The bandwidth was what you'd expect (3 megabits). However, the Orion IMUXes the carrier had provided were so flaky we ended up removing the whole setup and running individual T1's to the hub routers, as part of an overall re-engineering of the network. The carrier just could not get the circuits stable long-term with those IMUXes in there. They were also the ones who had designed the network with that equipment before we took over management ... go figure.

RE: How to Multiplex 3 T1s [7:4625]
In your particular case, due to the existing T1 ports on the 7206, I would guess at PPP multilink is the most cost effective way to go. But just FYI, you can put an IMA device (either a card in a Cisco router, or an external box such as Adtrans or a number of other vendors sell) and multiplex those T1 lines even if they are not native ATM - provided the endpoints of all the T1's are at the same two locations. If you use an external device, the handoff to the router is HSSI.

Multilink PPP will let you bind all three circuits, I'll see if I can scavenge up the link on CCO.cisco.com. For a slightly less complex solution, create 3 separate numbered links across the three t1's and put 3 equal cost routes pointing to the same destination on both ends.

Well if they really need to be bound to 1 ip, I suspect multilink pp is the way to go. Alternatively, you could just point the same static routes at all 3 and turn off caching if you really want to.
