Hi, I've been tasked with bonding some ATM ADSL links together into a multilink bundle. The objective is to enable customers to double their throughput by obtaining (2) DSL lines from us.
The head end is a 7206 (NPE200) running C7200-IS-M 12.3(15b). The CPE end is a Cisco 1841 running (C1841-IPBASE-M) 12.4(1c). Is it as simple as putting "ppp multilink" under Virtual-Template1 of the head-end and "ppp multilink" under the (2) Dialer interfaces of the CPE end? Will there be any problem allowing multiple customers to bond links with these configs? Maybe I need to specify a Multilink interface on the 7206 and create unique multilink groups for each customer? In the archives, someone also suggested putting "lcp renegotiation always" under vpdn-group 1 on the 7206 to allow the cpe and lns to re-negotiate for ppp multilink, if the cpe asks for it. I'm not sure if that's really needed in this case. I'm short on lab equipment so any experimentation I do has to be on the production equipment. Obviously I'm reticent to try anything out which will disrupt the many active links on the 7206. Thanks for any advice (or better yet, working configs!!) you can share.
