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 upon IPsec SA creation 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 IPsec RRI for an IPsec policy, the device deletes all IPsec SAs that are created
according to this IPsec policy. Upon IPsec SAs are renegotiated, the static routes are created.
When you 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.
