Opinions? CEF with ISP for multiple T1 connection

[russ.laplante]

A major ISP is trying to sell us a 4.5MB connection to the Internet by taking 3 separate T1s and aggregating the bandwidth with CEF. That sounds nice in theory, and we do use CEF, but I am a little hesitant to go with this since we are hosting web sites for close to 500 customers.

My primary concern is that we will have packets arriving on the other side out of order. Maybe this will not be a major issue at this point, but as things evolve, we may offer more multimedia off of these web sites or helpdesk interactive services.

Sound I tell them to take a hike and go with a provided that will set me up with an IMUX or MLPPP?

Opinions and experiences?

Thanks.

You will find people you swear by CEF and those that have been bitten by it. Same with MLPPP. Your concern about ordering would lead you towards CEF per destination load balancing.

See this link about CEF load balancing.

Hope it helps.
