Anthony, Usually for static IP assignments you would have to redistribute the connected/static (static for routes) prefixes into the routing protocol (I would recommend BGP) so that you advertise them as /32. No magic...

I currently have a 7301 acting as my BRAS running on 12.2(33)SRD3. I use the ISG feature to terminate PPPoE sessions on QinQ subinterfaces. The virtual templates associated with the bba groups use ip unnumbered loopback 0. The IP on loopback 0 is x.x.96.1/21 DHCP is configured for client IP address assignment using DHCP pools as relay agents to a central DHCP server. ip dhcp pool DHCP relay source x.x.96.0 255.255.248.0 class DHCP relay target x.x.111.5 I would now like to install a second 7301 for load balancing/redundancy. I currently trunk the QinQ vlans to the existing 7301 so I just do the same for the second 7301. On the second 7301 I assign a new /21 network for DHCP assignment. This works fine for dynamic IP assignment. My problem is that we have multiple customers with static IP address assignment from the DHCP server. How can I assign the same IP address to a certain client session if they login to either BRAS when each BRAS has a unique network associated with the loopback 0 interface. I was thinking mobile IP but I have not tested in the lab and not sure if it is a supported solution.
