Virtual Private Networks (VPN)
b. And a network interface. For example, to add an interface named dmvpn_tunnel_interface:
(config)> add network interface dmvpn_tunnel_interface
(config network interface dmvpn_tunnel_interface)>
c. Set the zone to internal:
(config network interface dmvpn_tunnel_interface)> zone internal
(config network interface dmvpn_tunnel_interface)>
d. Set the device to the IP tunnel created above:
(config network interface dmvpn_tunnel_interface)> device
/vpn/iptunnel/dmvpn_tunnel
(config network interface dmvpn_tunnel_interface)>
e. Set the IP address and netmask of the tunnel. The netmask must be set to /32. For
example, to set the IP address to 10.20.1.4/32:
(config network interface dmvpn_tunnel_interface)> ipv4 address
10.20.1.4/32
(config network interface dmvpn_tunnel_interface)>
5. Configure NHRP:
a. Type ... to return to the top level of the configuration schema:
(config network interface dmvpn_tunnel_interface)> ...
(config)>
b. Enable routing services:
(config)> network route service enable true
(config)>
c. Enable NHRP:
(config)> network route service nhrp enable true
(config)>
d. Add an NHRP network:
(config)> add network route service nhrp network end
(config network route service nhrp network 0)>
e. Set the interface to the interface that was created above:
(config network route service nhrp network 0)> interface dmvpn_tunnel_
interface
(config network route service nhrp network 0)>
