Hi: Guy
I appreciate all you have done. I get a lot of experience.
Nowdays, I plan to use a lookproof device to connect multi ISP.
Regards

??: RE: Cisco 6506 and BGP problem
Most of the packets are not switched by MSFC. The actual packets are
switched wither by PFC (or DFC). Depending on hardware PFC would either do
distributed CEF or mls flow switching. I trust in either case PFC hardware
will not be able to do per-packet. I do not dispute the idea though - on
average per source-destination pair loadbalancing should provide as good
distribution (and may even be better as it less likely to put the packets
out of the order).
Best regards,
Alexei

I don't see why it wouldn't. If you're using and MSFC/MSFC2 you can use CEF
for load balancing or even just equal-cost path load balancing (I'm using
Native IOS but I'm sure that running IOS on an MSFC on a 65xx in Hybrid mode
would use these features are they're IOS based). I think Brian's idea is a
perfect idea that's both simple and effective.

Brian,
My understanding is that 6506 doesn't support per-packet load balance.

Meng,
Why not just put two static default routes? With CEF you can load
balance between these routes on a per-packet or per-destination basis.

two ISP(using two 1000BaseT port) load balance, but Tel can't support BGP,
they worried statibility.
What kinds of solution and Could you give some suggestion and design.
