Hi all,

I have a client who wants to do load blancing between frame-relay and DSL/VPN line on the spoke site. The spoke has a WAN/Internet router with a frame-relay interface that connects to corp WAN at HQFRRouter (hub-and-spoke) and an ethernet (via DSL) that VPN to HQVPNRouter. HQFRRouter and HQVPNRouter are connected by a LAN.

Topology below:

RemoteRouter-FR-------WAN-------FR-HQFRRouter-----|
| LAN
ETH--DSL--------Internet-----DSL--ETH-HQVPNRouter-|

The requirement is to do load balancing between the frame and VPN/DSL.

My question is how do we enforce the packets sent from remote office to HQVPNRouter to return back the same router (ie not from the HQFRRouter)? otherwise the IPSec session will break (to my understanding). The traffic is claffied by TrafficShaper to DSCP values on both ends.

Can anyone shed lights what is the best way to solve this?

Thank you.
