Default command level
2: System level
Parameters
router-id: Router ID in IP address format.
Usage guidelines
To run IPv6 BGP protocol, a router must have a router ID, an unsigned 32-bit integer and the unique ID
of the router in the AS.
Specify a router ID manually, or the system selects the highest IPv4 address among loopback interface
addresses as the router ID. If no loopback interface addresses are available, the system selects the
highest IPv4 address among physical interface IPv4 addresses as the router ID. Specify a loopback
interface address as the router ID to enhance network reliability.
If the interface whose IPv4 address is selected as the router ID or the manual router ID is deleted, the
system selects a new router ID for the router.
Examples
# Specify the router ID of the router as 10.18.4.221.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] router-id 10.18.4.221
synchronization (IPv6 address family view)
Use synchronization to enable the synchronization between IPv6 BGP and IGP.
Use undo synchronization to disable the synchronization.
Syntax
synchronization
undo synchronization
Default
The feature is disabled. Upon receiving an IPv6 IBGP route, the BGP router only checks whether the next
hop is reachable before advertisement. If synchronization is enabled, the IBGP route can be advertised
to EBGP peers only when the route is also advertised by the IGP.
