[c-nsp] Beyond 1 Gbps

[Joe Loiacono]

We have a 6509 GigE link that is becoming saturated. The 6509 connects to 
a Juniper M10 and there is a firewall between them. In this situation, a 
migration to 10GigE looks too expensive.

So one would think EtherChannel. However, now both the firewall and the 
Juniper have to be able to do EtherChannel (I've seen the recent 
discussion on Fast Ether Channel vs. IEEE 802.3ad.)

Anyone have any experience in getting past 1GigE in a mixed environment 
like this?

PS - this configuration is fully redundant (2 each: 6509s, f/ws, Junipers) 
and the backup GigE is unused - could we somehow employ it? (The first 
concern here though is asymmetric routing and stateful firewalls)

Thanks,

Joe
