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 on page 10-4. 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 on
page 10-2 for more information.
BEFORE YOU BEGIN
Ensure that you have enabled the BGP feature (see the “Enabling the BGP Feature” section on
page 10-10).
BGP must be able to obtain a router ID (for example, a configured loopback address).
