I have a global MPLS BGP network. At this time all of the international sites have local internet access. So BGP handles all the corporate WAN connectivity and a default route to the local firewall handles the internet connectivity.
I was asked if I could route a particular office's internet traffic over BGP to another larger office.
My BGP cloud consists of RFC1918 addresses,(my office LANs) and my ISP's public addressing for WAN connectivity,(address provided by ISP for eBGP peering with their edge routers).
How can I send non corporate WAN traffic into the cloud to a particular office firewall on the office LAN?
