Usage guidelines
IPsec RRI is usually used on a gateway device at the headquarters side in an IPsec VPN.
After IPsec RRI is enabled for an IPsec policy or an IPsec policy template on a gateway device, the
gateway device automatically creates a static route when an IPsec SA is created according to this IPsec
policy or IPsec policy template.
In the static route, the destination IP address is the protected peer private network, and the next hop is the
IP address of the remote tunnel interface.
When you enable or disable IPsec RRI for an IPsec policy, the device deletes all IPsec SAs that are created
according to this IPsec policy, and the associated static routes.
To display the static routes created by RRI, use the display ip routing-table command.
Examples
# Enable IPsec RRI to create a static route according to the IPsec SA negotiated by the specified IPsec
policy. The destination IP address is the protected peer private network 3.0.0.0/24, and the next hop is
the IP address (1.1.1.2) of the remote tunnel interface.
