synchronization (BGP view)

Syntax
synchronization
undo synchronization
View
BGP view
Default level
2: System level
Parameters
None
Description
Use synchronization to enable the synchronization between the BGP and IGP routes.
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,
BGP speakers in the AS cannot advertise routing information to other ASs unless all routers in the
AS know the latest routing information.
When a BGP router receives an IBGP route, it checks only whether the next hop is reachable by
default. If the synchronization is enabled, the IBGP route is synchronized and advertised to EBGP
peers only when the route is also advertised by IGP. Otherwise, the IBGP route cannot be advertised
to EBGP peers.
