Use theÂ async default routing command to define the default behavior for router-to-router communication over connections to the AUX port configured as an asynchronous interface. This command is commonly used to enable two routers to communicate over an async dial backup link.
To require a remote user to manually configure routing over connections to the AUX port configured as an asynchronous interface, use theÂ async dynamic routing command.
The following example enables routing over asynchronous interface 0:
interface async 0
Â async default routing
|async dynamic routing||Enables manually configured routing on an asynchronous interface.|
