   You see the following prompt:

   bgp>
   

2. Type enable

   This turns the BGP routing process on and switches to global configuration mode.

3. Specify a list of networks for the BGP routing process.

   Option	Description
   bgp#configure terminal	Enables the BGP configuration mode which places you in the Router Configuration mode and allows you to configure from the terminal.
   bgp(config)#router bgp AS number	Allows you to configure and start the BGP routing process. The Autonomous System (AS) number is the number of the local AS that your Sophos Firewall is a member of.
   bgp(config-router)#network ip-address	Specify the ip-address with the subnet information of the network to be advertised. IP Addresses and network masks or prefixes of networks to advertise to BGP peers. Sophos Firewall may have a physical or VLAN interface connected to those networks.
   bgp(config-router)#no bgp ebgp-requires-policy	When you configure BGP from the web admin console, the command is applied by default. When you configure BGP on the CLI, you can run this command to get additional information. When you apply the Global configuration settings on the web admin console, the firewall removes your changes to the default settings.
   bgp(config-router)#bgp log-neighbor-changes	When you configure BGP from the web admin console, the command is applied by default. When you configure BGP on the CLI, you can run this command to get additional information.

   bgp(config-router)#show running-config	Shows the configuration. By default, the router ID is the IP address of the Sophos Firewall. The router ID is used to identify the Sophos Firewall to other BGP routers. The router ID can be an integer or can take a form similar to an IP address A.B.C.D.
   bgp(config-router)#end	Exits from the router configuration mode and places you into the enable mode.
   bgp#exit	Exits to the router management menu.
