Weidong,
For a border router, a 7200 is more than adequate for most WAN
applications. Both will handle OC12 connectivity. A 6500 may now support
WAN modules, but it's real advantage is aggregating and routing dozens of
gigabit ethernet connections. Picking the right tool for the job is key.
Processor speed doesn't really matter, as they're totally different
architectures. 400kpps per second with 64 byte frames is about 200mbit.
Given a more realistic 500 byte frames, that's 1.6 gigabit, way more than
most WAN speed requirements. Sure the 6500 can do hundreds of times more
than that, but there's no need to/from the WAN.

Subject: OT: 6509 or 7200, which is better for border router?
Hello,
I'm in a process of designing a data centre. I got several 7200vxr and 6509
at my disposal.
1. What kind of cpu is 7200 running? NPE400 or R7000?
2. If both 6509 and 7200vxr are running R7000 CPU, then 7200vxr seems better
from an old-fashioned router point of view (because it's running at 350Mhz,
while 6509 is at 300Mhz). But 6509's RP is actually a 7600 router, how can
it be slower than 7200?
3. From CCO, I got:
NPE-400 - performance up to 400 Kpps ---------for 7200
Service Performance 6 Mpps--------------for 7600
Does this mean 6509 is 1500 times faster that 7200 when they are doing
packet switching?
4. 6509's strongest point is MLS, is this feature important in a border
router? 6509 or 7200, which is better for a border router's role?
Many thanks,
Weidong
