[c-nsp] Sizing a router for full feed (once and for all)

[Joost greene]

Hello,

I always see people asking if their routers can handle BGP and alot of times
the answer isnt just memory, sometimes TCAM limitation (3750 for e.g.) maybe
other cases, what i want to have is some sort of check list for this, my
case is a :



IOS (tm) 3700 Software (C3745-JK9O3S-M), Version 12.3(9), RELEASE SOFTWARE
(fc2)
System image file is "flash:c3745-jk9o3s-mz.123-9.bin"

cisco 3745 (R7000) processor (revision 2.0) with 250880K/11264K bytes of
memory.
R7000 CPU at 350MHz, Implementation 39, Rev 3.3, 256KB L2, 2048KB L3 Cache
2 FastEthernet/IEEE 802.3 interface(s)
8 Serial network interface(s)
DRAM configuration is 64 bits wide with parity disabled.
151K bytes of non-volatile configuration memory.
125184K bytes of ATA System CompactFlash (Read/Write)
125184K bytes of ATA Slot0 CompactFlash (Read/Write)


I want to know if it can handle two full tabes and more than that how do i
do this math next time ?

Thanks
Joost
