Description
Use summary automatic to enable automatic summarization for redistributed subnets.
Use undo summary automatic to disable automatic summarization.
By default, automatic summarization is disabled.
The default routes and the routes imported through the network command cannot be automatically
summarized.
The summary automatic command helps IPv4 MBGP limit the number of routes redistributed from IGP.
Examples
