Configuring a BGP Neighbor Group
Perform this task to configure BGP neighbor groups and apply the neighbor group configuration to a
neighbor.
After a neighbor group is configured, each neighbor can inherit the configuration through the use
command. If a neighbor is configured to use a neighbor group, the neighbor (by default) inherits the
entire configuration of the neighbor group, which includes the address family-independent and address
family-dependent configurations. The inherited configuration can be overridden if you directly
configure commands for the neighbor or configure session groups or address family groups through the
use command.
From neighbor group configuration mode, you can configure address family-independent parameters for
the neighbor group. Use the address-family command when in the neighbor group configuration mode.
After specifying the neighbor group name using the neighbor group command, you can assign options
to the neighbor group.
