You could run routing protocol inside the (DMVPN) tunnel like OSPF and redistribute using MP-BGP.
router ospf 1 vrf CUSTOMER1 <---VRF instance of OSPF network [tunnel interface ip network] area 0 redistribute bgp 65535 subnets route-map redis-bgp-vrf-CUSTOMER1-to-ospf ! Router ospf 2 Network [tunnel interface ip network] area 0 ! router bgp 65535 address-family ipv4 vrf CUSTOMER1 redistribute ospf 1 vrf CUSTOMER1 route-map redis-ospf-to-bgp-vrf Regards, Luan Nguyen Chesapeake NetCraftsmen, LLC. www.NetCraftsmen.net -----Original Message----- From: Tim Durack [mailto:[email protected]] Sent: Wednesday, December 17, 2008 1:21 PM To: Luan Nguyen Cc: [email protected] Subject: Re: [c-nsp] MPLS-VPN migration On Wed, Dec 17, 2008 at 12:25 PM, Luan Nguyen <[email protected]> wrote: > Let me try thinking out loud :) > There BGP support for IP prefix import into VRF table: > http://www.cisco.com/en/US/docs/ios/12_3t/12_3t14/feature/guide/gt_bgivt.htm > l > You could use static routes as well. Looked at that. Trouble is the static routes have to specify next-hop, which isn't going to be very scalable for directly-connected VLAN interfaces. > For dynamic, some people create two tunnels, same router, same subnet, > sourced from different loopbacks.

I guess that could work. I was hoping to do something along the lines of: http://www.cisco.com/en/US/docs/ios/iproute/configuration/guide/bgp_router_i d_ps6017_TSD_Products_Configuration_Guide_Chapter.html#wp1055073 But it looks like this only works for VRF<->VRF BGP sessions, not VRF<->GLOBAL.
