My client has a central site with a cisco pix for their main internet and site to site ipsec vpn termination, they also have an mpls cloud with 1841 on each site. Each remote site has only one internet connection and the mpls connection, if the mpls connection fails the internet connection creates an ipsec vpn and creates a backup tunnel.
the problem is i want to route certain traffic over the mpls and other non essential traffic over vpn. Now i have been told to use GRE and understand the examples on cisco website but cant seem to get my head around the exact way to do it when there is a pix terminating the vpn's So in short the router on the remote sites has an mpls and internet connection (for vpn) the vpn terminates on the pix and the mpls terminates on an 1841 on the central site Where do i terminate the GRE tunnel or do i ?
the 1841 has an address of .254 and is the main gateway to all networks the pix 515e is .243 and handles vpn and internet traffic. does this explain it or would a digram suit better?
