I'm attempting to use OpenNHRP on a linux box to connect with a Cisco Router.
I want to allow GRE tunnels from the linux box to the Cisco router dynamically, but I'm not implementing DMVPN on the Cisco router.
I keep receiving the [Peer up script failed Exit Status: 1] error from OpenNHRP, which I've learned is due to no SA being negotiated.
I don't think I need an SA since I'm doing these GRE tunnels in the clear, and wondering whether anyone knew a way around this, or another way to do NHRP peers from a linux box.
interface gre1 map 10.10.10.1/24 172.17.6.2 register cisco
interface tunnel10 ip address 10.10.10.1 255.255.255.0 no ip redirects ip mtu 1400 ip nhrp map multicast ip nhrp network-id 2 tunnel source 172.17.6.2 tunnel mode gre multipoint
My GRE tunnels work fine when I statically assign endpoints to the GRE tunnels, but I need them to be dynamic for this situation.
