Interconnecting Switches, backup ISDN, trunk 802.1q

Hello

I woukd like to conect two remote switches with a ISDN backup line.

My idea is to configure two ISDN routers (7200)with support of trunk IEEE 802.1q

Can anyone help me to say if it is possible, and how to configure it?

Thanks

I haven’t done it but it seems like it should work. This is the config for the isdn backup. 802.1q? I don’t know.http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/12cgcr/dial_r/drprt4/drdbaks.htm

Yes,

Trunk traffic over WAN Links strongly discouraged unless u have strong reason.
