WCCP: Is dot1Q trunking needed on Router I/F to avoid redirection loop

Hi everyone,

I have a question how configure Router I/F to avoid redirection loop.

I understand Router and WAE must not be attached to the same segment to avoid redirection loop as written in the Quick Configuration Guide.

However the sample configuration in Quick Configuration Guide does not show necessity of whether VLAN trunking is needed or not on the Router port and Switch under following environment;

Client

|

|

Switch --- WAE

|

|

Router

|

|

WAN

|

|

Router

|

|

Switch --- WAE

|

|

Server

I think .1Q trunking is need to avoid redirection loop and it is a only way to achieve it in case of the router (core and/or edge) has just two interfaces.

And if the router does not support .1Q trunking due to hardware limitation or software limitation, I need to get the router had more one dedicated interface to redirect WAE by adding additional network module/card if it can.

I am afraid that if the router does not support .1Q trunking and router has up to two interfaces, I need to purchase/prepare another router to achieve it or not.

Is my understanding correct ?

Or are there any method to avoid redirection loop other than using .1Q trunk or adding interface that is remains just two interfaces ?

Would you please let me know your assistance ?

Best regards,
