oh, please please name the router vendor that has 4gb of 'ram'
(tcam/fpga/asic-'memory') on the 'linecard'. Oh, can't come up with one?
One wonders why that is? If the solution were as simple as: "Joe, add
1.21jigawatts of memory to the linecard so we can support +1M routes"
Don't you think the vendor would have done this to get people to stop
bitching at them?

memory, 3. TCAM memory (damn costly stuff )<BR><BR>And as for the number of
routes to be support -Right now venodrs do support close to 500K routes - ask
me to name the vendor (notice i did not say Vendors here) and i will be happy
to name.But, yes to do something like 1M routes - ahem mighty tricky stuff
aint it, but, does any one have 1M active routes in his table as of today
(notice how iam trying to evade commenting ;) you cant haul me for saying
this)<BR>

In YOUR network you don't... I'd venture to guess there are quite a few
