I have a standard hub and spoke network trying to use DMVPN. My CE router
hands off to a carrier network and the carrier network is using seperate L3
VPNS and VRF's. CE to CE I am running EIGRP. When I configure my spoke as
a point to point gre tunnel and the hub as a point to point gre tunnel, all
works. When I change them both to a Mgre, it does not. If I change the
spoke to MGRE and the hub as P2P, it works. Below are the tunnel
configs...any clues to what is not working and why?
CE "spoke"
interface Tunnel0
ip address 50.50.50.2 255.255.255.0
no ip redirects
ip mtu 1416
ip nhrp authentication cisco
ip nhrp map 50.50.50.1 10.10.5.2
ip nhrp map multicast 10.10.5.2
ip nhrp network-id 99
ip nhrp nhs 50.50.50.1
tunnel source FastEthernet0/0
tunnel mode gre multipoint
tunnel protection ipsec profile VPN
end
CE "hub"
interface Tunnel0
ip address 50.50.50.1 255.255.255.0
ip mtu 1416
ip nhrp authentication cisco
ip nhrp map multicast dynamic
ip nhrp network-id 99
tunnel source GigabitEthernet0/1
tunnel destination 10.10.8.2
tunnel protection ipsec profile VPN
