There is a L2L tunnel from the 515 Pix (Main office) to another Pix in Location B.

There is another L2L tunnel from Location A to Main Office in the 506e. My question is:

how do I route the traffic from 506 Tunnel from Location A to 515 Tunnel tocation B without adding any other device or hardware? 

What commands/settings would I need to modify in the 506 and the 515 to make this possible?

Thanks

John
