IPSec Branch Office configuration

The branch office feature allows you to configure an IPsec tunnel connection between two private
networks. Typically, one private network is behind a locally configured switch while the other is
behind a remote switch. A branch office configuration allows you to configure the accessible
subnetworks behind each switch. The configuration also contains the information that is necessary
to set up the connection, such as the switch IP addresses, encryption types and authentication
methods.
You can do the following with Branch Office IPSec tunnels:
