BGP router
First of all you must configure BGP router with router bgp
command. To configure BGP router, you need AS number. AS number is an
identification of autonomous system. BGP protocol uses the AS number
for detecting whether the BGP connection is internal one or external one.
Enable a BGP protocol process with the specified asn. After
this statement you can input any BGP Commands. You can not
create different BGP process under different asn without
specifying multiple-instance (see Multiple instance).

This command specifies the router-ID. If bgpd connects to zebra it gets
interface and address information. In that case default router ID value
is selected as the largest IP Address of the interfaces. When
router zebra is not enabled bgpd can't get interface information
so router-id is set to 0.0.0.0. So please set router-id by hand.
