You can configure BGP4 unicast routes from the address-family IPv4 unicast configuration level.
device(config)# router bgp device(config-bgp-router)# address-family ipv4 unicast device(config-bgp-ipv4u)#
Note
The commands that are available from the address-family IPv4 unicast configuration level are also available from the address-family IPv6 unicast configuration level. Each configuration level allows you to access commands that apply only to that particular address family.
