Configuring the Router
Dec 18, 2013
The appliance negotiates WCCP-GRE or WCCP-L2 automatically. The main choice is between
unicast operation
(in which
the appliance is configured with the IP address of each router), or multicast operation (in which both the appliance and the
routers are configured with the multicast address.)
Normal Normal (Unicast ) operat ion (Unicast ) operat ion— For normal operation, the procedure is to declare WCCP version 2 and the WCCP group ID
for the router as a whole, then enable redirection on each WAN interface. Following is a Cisco IOS example:
config term
ip wccp version 2
! We will configure the appliance to use group 51 for TCP and 52 for UDP.
ip wccp 51
ip wccp 52
! Repeat the following three lines for each WAN interface
! you wish to accelerate:
interface your_wan_interface
! If Reverse Path Forwarding is enabled (with an ip verify unicast
! source reachable” statement), delete or comment out the statement:
! ip verify unicast source reachable-via any
! Repeat on all ports.
ip wccp 51 redirect out
ip wccp 51 redirect in
ip wccp 52 redirect out
ip wccp 52 redirect in
! If the appliance is inline with one of the router interfaces
! (NOT SUPPORTED), add the following line for that interface
! to prevent loops:
ip wccp redirect exclude in
^Z
If multiple routers are to use the same appliance, each is configured as shown above, using either the same service groups
or different ones.
Mult icast operat ion Mult icast operat ion— When giving the appliance and each router a multicast address, the configuration is slightly
different than for normal operation. Following is a Cisco IOS example:
config term
ip wccp version 2
ip wccp 51 group-address 225.0.0.1
! Repeat the following three lines for each WAN interface
! you wish to accelerate:
interface your_wan_interface
! If Reverse Path Forwarding is enabled (with an ip verify unicast
! source reachable” statement), delete or comment out the statement:
