DMVPN - Redistribute EIGRP to BGP

need assistance with DMVPN solution. Remote/spoke routers (2811s) will connect via to one of two DMVPN hub routers (7206s - no load sharing, just hub redundancy). Spoke to hub will be using EIGRP. DMVPN hub routers will then redistribute spoke router's EIGRP networks into BGP. Hub routers will have EBGP relationship with company's edge BGP routers. Current infrastructure utilizes 5xx series firewalls at spoke/remote sites that IPSec VPN to one or another hub 3030 VPN concentrators. Project is to leverage from IPSec solution to DMVPN solution. Looking for documentation that supports EIGRP routing process between spoke to DMVPN hub router. Then, redistributing EIGRP on DMVPN router into BGP. Thanks,

Re: DMVPN - Redistribute EIGRP to BGP

Hello Kevin,

here it is a link to DMVPN SRND

http://www.cisco.com/en/US/docs/solutions/Enterprise/WAN_and_MAN/DMVPDG.html

redistribution of EIGRP into BGP requires care: if possible avoid to perform mutual redistribution on the two hub routers.

if really needed you should use route-tags to avoid unwanted feedback and possible routing loops during topology changes.

Consider also the use of iBGP instead of EIGRP as the routing protocol in the DMVPN it may help in simplyfing the solution.

Hope to help

Giuseppe
