Synchronization (Ipv6 Address Family View) - HP 6125G Command Reference Manual

Description
Use router-id to specify a router ID for the router.
Use undo router-id to remove a router ID.
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.
You can specify a router ID manually. Otherwise, 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

Syntax

View
IPv6 address family view
Default level
2: System level
Parameters
None
Description
Use synchronization to enable the synchronization between IPv6 BGP and IGP.
Use undo synchronization to disable the synchronization.
The feature is disabled by default.
With this feature enabled and when a non-BGP router is responsible for forwarding packets in an AS,
IPv6 BGP speakers in the AS cannot advertise routing information to other ASs unless all routers in the AS
know the latest routing information.
By default, 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.
Examples
# Enable the route synchronization between IPv6 BGP and IGP.
