What does Comcast do if you exceed 20 meg? We were told by AT&T that anything over \
the specified limit would be dropped, so we use rate limiting...not sure if Comcast \
does the same.

We are about to accept a 20MEG Ethernet feed via Comcast and their fiber plant as \
well as a BGP feed across the same link.

I have a space GIGE interface on a 7206VXR and would like to know best practice for \
deploying for optimal performance across this interface.

Any ideas and or direction would be extremely helpful as we are seeing some real \
issues such as.

Direct connect (without BGP) to the CPE from Comcast (Fiber to Ethernet) via a laptop \
gives the level of performance we would expect, However as soon as we terminate to \
our router via the GIGE which is set to 100MB full duplex and all flow control turned \
off (Negotiation auto) per Comcast and connect up via a 100MB fast Ethernet interface \
directly connected we get a fraction of the speed when direct connected.

Ideas?
