To enable BGP:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Configure a global router ID. router id router-id

By default, no global router ID is
configured, and BGP uses the
highest loopback interface IP

address—if any—as the router ID. If

no loopback interface IP address is

available, BGP uses the highest
physical interface IP address as the

route ID regardless of the interface

status.

3.

Enable BGP and enter BGP
view or BGP-VPN instance

view.

Enable BGP and enter BGP
view:

bgp as-number

Enable BGP and enter

BGP-VPN instance view:

a.

bgp as-number

b.

ip vpn-instance

vpn-instance-name

By default, BGP is not enabled.
A router can reside in only one AS,

so the router can run only one BGP
process.
To enter BGP-VPN instance view, the
specified VPN instance must already

exist and have the route distinguisher
(RD) configured. For more

information, see MPLS Configuration

Guide.

4.

Configure the router ID.

router-id { router-id |
auto-select }

By default, the global router ID is
used.
The auto-select keyword is

supported only in BGP-VPN instance
view.
