Configuring BGP
The term "router" in this document refers to both routers and LB modules.
Border Gateway Protocol (BGP) is an exterior gateway protocol. It is called internal BGP (IBGP) when it
runs within an AS and called external BGP (EBGP) when it runs between ASs.
The current version in use is BGP-4 (RFC 4271). Unless otherwise stated, BGP refers to BGP-4 in this
document.
Configuring BGP in the Web interface
Recommended configuration procedure
The Web interface supports configuring only basic BGP functions, such as enabling BGP, configuring
BGP peers, and enabling BGP to redistribute static routes. To control BGP route generation and
advertisement and BGP path selection, perform the configurations at the command line interface (CLI).
For more information, see System Maintenance Configuration Guide.

Remarks
1. Configuring BGP globally
Required.
Enable BGP and specify an AS number, and configure BGP to
redistribute static routes.
2. Configuring BGP peer
Required.
Configure the IP address and AS number for the BGP peer.
3. Displaying BGP peer information
Optional.
Display the IP address, AS number, version and current state
of the BGP peer.
To enable a router to run BGP, you must specify a router ID, the unique identifier of the router in the AS.
By default, if no global router ID is configured, the highest loopback interface IP address, if any, is used
as the router ID. If no loopback interface IP address is available, the highest physical interface IP address
is used, regardless of the interface status. Use loopback interface IP address as a router ID to increase the
network availability.
Configuring BGP globally
1. Select Network > BGP from the navigation tree.
The BGP global configuration page appears.
