my company has 3 major sites, we wish to configure channelised E3 along with multilink so that we have 3 different links to 3 different remote sites so that there traffic travels across seperatly. the 1st will have 8 E1s bundled together for one site the 2nd will have 4 E1s bundled for the 2nd destination, 2 E1s will be bundled for the last destination and the remaining 2 E1s will be used fpr back up .


Is this possible ? How? is it also version dependent i m workin on 12.2 IOS on cisco 7206 VXR. Please help urgently.

Thanks.

The Distributed Multilink Point to Point Protocol (dMLP) feature allows you to combine full or fractional T1/E1 lines in a line card (VIP, FlexWAN) on a Cisco 7500 or 7600 series router into a bundle that has the combined bandwidth of multiple links.Refer URL

hi,


here you can creat three different MLPPP interface and you can add the E1 link as per your requirement to the appropriate group... so here in first MLPPP you will add 8E1

in second MLPPP you will add 4E1 and in

third you will add 2E1... and now you want to configure other two E1 for back up off all this three then you can go for Distributed MLPPP as given in the privious post...

"The Distributed Multilink Point to Point Protocol (dMLP) feature allows you to combine full or fractional T1/E1 lines in a line card (VIP, FlexWAN) on a Cisco 7500 or 7600 series router into a bundle that has the combined bandwidth of multiple links. You use a distributed MLP Bundle to do this. A user can choose the number of bundles in a router and the number of links per bundle. This allows the user to increase the bandwidth of network links beyond that of a single T1/E1 line without the need to purchase a T3 line. In non-dMLP, all of the packets are switched by the Route Processor (RP); therefore, this implementation impacts performance of the RP, with high CPU utilization for only a few T1/E1 lines running MLP. With dMLP, the total number of bundles that can be handled on the router is increased, as the data path is handled and limited by line card CPU and memory. dMLP allows you to bundle fractional T1/E1, starting from DS0 (64 Kbps) onwards."


Hope this will help you
