Creating a BGP Instance

You can create a BGP instance and assign a router ID to the BGP instance. See the “BGP Router Identifier” section. Cisco NX-OS supports 2-byte or 4-byte autonomous system (AS) numbers in plain-text notation or as.dot notation. See the “4-Byte AS Number Support” section for more information.
BEFORE YOU BEGIN

Ensure that you have enabled the BGP feature (see the “Enabling the BGP Feature” section).

BGP must be able to obtain a router ID (for example, a configured loopback address).

SUMMARY STEPS

configure terminal
router bgp autonomous-system-number
(Optional) router-id ip-address
address-family ipv4 { unicast | multicast }
(Optional) network ip-prefix [ route-map map-name ]
(Optional) show bgp all
(Optional) copy running-config startup-config
