Configuring site-to-site VPN via the CLI
To configure a site-to-site VPN with two static IP controllers via the CLI, issue the following commands:
crypto-local ipsec-map <name> <priority>
src-net <ipaddr> <mask>
dst-net <ipaddr> <mask>
peer-ip <ipaddr>
vlan <id>
pre-connect enable|disable
trusted enable
For certificates:
set ca-certificate <cacert-name>
set server-certificate <cert-name>
crypto isakmp policy <priority>
encryption {3des|aes128|aes192|aes256|des}
authentication rsa-sig
group {1|2}
hash {md5|sha}
lifetime <seconds>
For preshared key:
crypto-local isakmp key <key> address <ipaddr> netmask <mask>
crypto isakmp policy <priority>
encryption {3des|aes128|aes192|aes256|des}
authentication pre-share
group {1|2}
hash {md5|sha}
lifetime <seconds>
To configure site-to-site VPN with a static and a dynamically addressed controller that initiates IKE Aggressive-
mode for Site-Site VPN:
crypto-local ipsec-map <name> <priority>
src-net <ipaddr> <mask>
dst-net <ipaddr> <mask>
peer-ip <ipaddr>
local-fqdn <local_id_fqdn>
vlan <id>
