Bandwidth between the 6509 MSFC and switch.

On the 6509 port 15/1 MSFC router port indicates a bandwidth of 1gig. Is this the total bandwidth available between the switch and router? Does it make sense to have a 2gig backbone between switches only to have traffic limited to 1gig when it passes through the MSFC ?

Re: Bandwidth between the 6509 MSFC and switch.

MLS and Hardware CEF are intended to prevent traffic from having to go between the MSFC and Switch. The only traffic that needs to go to the MSFC is initial flows, broadcast packets, control multicast packets. Routing is actually handled in ASICs on line cards and the supervisor of the Cat6k.

Yes, it is 1 Gigabit (2GBPS full-duplex). The MSFC2 can only process 650kpps anyway.
