Synchronizing Routes
By default, the routing switch does not wait until the IGPs in the local AS have fully exchanged route information before BGP4 advertises the routes to its remote BGP4 neighbors. The routing switch advertises routes to its remote BGP4 neighbors regardless of whether the routes are learned or have already been propagated throughout the local AS.
If you want the routing switch to wait until the IGPs in the local AS have fully exchanged route information before BGP4 advertises the routes to its remote BGP4 neighbors, enable synchronization.
To enable synchronization, use either of the following methods.
USING THE CLI
To enable synchronization, enter the following command:
To disable synchronization again, enter the following command:
Syntax: [no] synchronization

Automatically Summarizing Subnet Routes Into Class A, B, or C Networks
The auto summary feature summarizes the routes it redistributes from IGP to BGP4. The routing switch summarizes subnets into their natural class A, B, or C networks. For example, if an AS contains subnets 1.1.0.0, 1.2.0.0, and 1.3.0.0 with the network mask 255.255.0.0, the auto summary feature summarizes the subnets in its advertisements to BGP4 neighbors as 1.0.0.0/8.
The auto summary feature is disabled by default. If you want to enable the feature, use either of the following methods.
