Friends,

 

Thanks for some of the replies sent already!

 

I am also confused how a VIP can have a bandwidth capacity 750Mbps and a Packet forwardingrate of 200,000pps as stated in the datasheet.

 

As per my calculations, 64 byte sized packets would need 160,000pps on 100 Mbps ethernet, 1.6Mill-pps on 1 Gigabit Ethernet.

 

So it should be much more for 750Mbps.

 

Moreover where can one plug in the Gigabit Ethernet interfaces if the max VIP-6 200,000pps?

 

Sorry for a repeat post on the same thread.

 

I am thinking of asking my vendor for 1.6Mill-pps per VIP. Is this feasable?

Friends,

 

On the cisco 7500 series routers with 1GB RAM and the RSP-16, what is the maximum observed number for number of Multiprotocol-BGP routes?

 

Can one also share the number of VRFs and the number of routes per VRF on the same?

 

Similarly on the 7500, the white paper says that :

"In a dual RSP configuration, the Cisco 7500 will give the user the ability to double packet memory and increase aggregate switching performance. "

 

Has anyone got Dual RSP working somewhere?

Morover, do both RSPs function for "route lookups" simultaneously or is it one at a time?

 

Can a user plug away the RSPs and switching will still happen?

 

In other words, does each VIP/CEF database have the copy of the entire "forwarding table"?
