Hi all,

A quick question.

When can BGP synchronization be disabled?

Thank.

Hi Hobbit,

The synchronization feature is used to check the IGP routing table before IBGP routes are added to the routing table and advertised to EBGP peers. This prevents blackhole routes. Therefore, theoretically, when BGP establishes full-mesh connections, BGP synchronization can be disabled.

In fact, on Huawei devices, synchronization between BGP and an IGP is disabled by default and cannot be modified.

I hope this helps.
