synchronization (IPv6 address family view)

Syntax
synchronization
undo synchronization
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.
