R3303-HP HSR6800 Routers Layer 3 - IP Routing Configuration Guide

206
Step Command Remarks
2. Configure a global router ID.
router id router-id
Optional.
By default, no global router ID is
configured. BGP uses the highest
loopback interface IP address as the
router ID. If no loopback interface IP
address is available, BGP uses the
highest physical interface IP address
as the router ID regardless of the
interface status.
3. Enable BGP and enter BGP
view.
bgp as-number
Not enabled by default.
A router can reside in only one AS,
so the router can run only one BGP
process.
4. Specify a router ID.
router-id router-id
Optional.
By default, the global router ID is
used.
