Hi Alexei,
Thanks for the reply. The reason I wanted to keep Be at 0 was becuase the
question wants us to configure our interface running FR for RATE LIMITING.
So is setting Be to 0 the right interpretation for this?
Secondly, pls help to answer one more question:
R1----------------------------SW------------------------------Web Caching
System
R1 must intercept the http traffic coming to its ethernet interface and
redirect it towards the Web Caching engine. So first I'll use the following
two commands,
ip wccp web-cache
interface e0
ip wccp web-cache redirect out
Now since Im using the same interface (R1 e0) for both incoming web traffic
and outgoing web cache redirection, will it be necessary to use the command
int e0
*ip route-cache same-interface*
Will I need the above mentioned ip route-cache command or any additional
commands to meet the requirement of this question?
Thanks in advance,
Cheers!!!
Salman
