maybe I am wrong, but with high end switchrouter I thought that routing
protocols are handled by IOS by the cpu - after calculated, the topology
is programmed in e.g. TCAM memory.
That's the *point* - the CPU is what's vulnerable here. A suggestion was made to
replace the CPU with an ASIC or FPGA. I pointed out that if you did that, then
the ASIC would have to do BGP4, because otherwise there'd not be a routing table
loaded in the TCAM memory for the line cards to use....
