ask Cisco ;-)

yes - see my previous mail & comments by Oded Comay <comay@post.tau.ac.il>
Oded isn't on the NSP list you may want to CC him

-- Please note that tests using new features in IOS 12.0S showed a much improved performance when using policy routing and GRE tunneling (see below). To summarize, the 7500 in the tested configuration was seated in a loop, such that packets flowed both ways. We were able to squeeze 45K PPS on each direction (I think some people count this as 4x45K= 190K PPS, as packets are counted both incoming and outgoing). -- the routers where 7500's with RSP4 & a mixture of VIP2/40 & VIP2/50 you really should read Oded's (LONG) Email - sent earlier to the list AFAIK the GRE tunnel runs on the RSP & the policy routing on the VIP's so you can do capacity planning by VIP CPU onlyRafi > > Ed > > -- > On Tue, Jan 11, 2000 at 07:08:05AM -0800, Barry Raveendran Greene said: > > Hello Ed, > > > > Try Netflow Policy Routing: > > > > http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120 > > t/120t3/policyrt.htm > > > > Barry > >
