5.10.6 Configure synchronization between BGP and IGPs
If your autonomous system will be passing traffic through it from another autonomous system to a third autonomous
system, it is very important that your autonomous system be consistent about the routes that it advertises. For example, if
your BGP were to advertise a route before all routers in your network had learned about the route through your IGP, your
autonomous system could receive traffic that some routers cannot yet route. To prevent this from happening, BGP must
wait until the IGP has propagated routing information across your autonomous system. This causes BGP to be
synchronized with the IGP. Synchronization is enabled by default.
In some cases, you do not need synchronization. If you will not be passing traffic from a different autonomous system
through your autonomous system, or if all routers in your autonomous system will be running BGP, you can disable
synchronization. Disabling this feature can allow you to carry fewer routes in your IGP and allow BGP to converge more
quickly. To disable synchronization, use the following command in router configuration mode:
Command Purpose
Synchronization (undo) Disable synchronization between BGP and an IGP.
