routing application to stop denial of service attacks from remote hosts on the Internet.
Configuring BGP4
Once you activate BGP4, you can configure the BGP4 options. There are two configuration levels:
global and address family.
At the global level, all BGP4 configurations apply to IPv4 and IPv6. Enter this layer using the device
BGP4 command
Under the global level, you specify an address family. Address families separate IPv4 and IPv6
BGP4 configurations. Go to this level by entering the address-family command at the device BGP4
level. The command requires you to specify the IPv4 or IPv6 network protocol.
The address family command also requires you to select a sub-address family, which is the type of
routes for the configuration. Specify multicast or unicast routes.
