Multilink bundling issue


i hve pasted the o/p of my sh ver taken out from my cisco 3660 routers i m planning to run 3*2Mbps in multilink between 2 locations which r having the same query is will the routers able to handle these addition to this we r running bgp (both EBGP/IBGP) and OSPF with other peers already in these routers.

right now the cpu util is coming under 13% on average basis.

Re: Multilink bundling issue

Running PPP multilink on 3 extra E1's is not that much of a load for the 3660. It's ok.

Re: Multilink bundling issue

Three E1s bundled with MLPPP might add a fair amount of CPU overhead, IMHP (In My Humble Prediction). Tough to predict, of course. Depends not only on all other configured features but, especially, the traffic load. If you find CPU utilization high on one end or the other, I highly recommend turning off MLPPP frame fragmentation. In the MLPPP interface configuration, the command is "no ppp multilink fragmentation" or "ppp multilink fragment disable," depending on the IOS version. I'm not certain which one with your version, but the former one is the older command.
