VPN Technologies

How do you configure the preshared key Test for every remote VPN router in a DMVPN deployment that uses GRE over IPsec?

  • A authentication pre-share Test address 0.0.0.0 0.0.0.0
  • B set pre-share Test address 0.0.0.0 0.0.0.0
  • C crypto ipsec key Test address 0.0.0.0 0.0.0.0
  • D crypto isakmp key Test address 0.0.0.0 0.0.0.0
Explanation

For Cisco IOS IKEv1, crypto isakmp key defines a preshared key for an ISAKMP peer. Using address 0.0.0.0 0.0.0.0 matches any remote peer, allowing the same key to be used by all dynamic DMVPN remote routers.
