To enable manually configured routing on an asynchronous interface, use the async dynamic routing interface configuration command. Use the no form of this command to disable routing protocols; static routing is still used.

The async dynamic routing command is commonly used to manually bring up PPP from an EXEC session.
The following example manually configures routing on asynchronous interface 1. Theip tcpheader-compression passive command enables Van Jacobson TCP header compression and prevents transmission of compressed packets until a compressed packet arrives from the asynchronous link.

A remote user who establishes a PPP or SLIP connection to this asynchronous interface can enable routing by using the/routing switch or the ppp/routing command. However, if you want to establish routing by default on connections to an asynchronous interface, use the async default routingcommand when you configure the interface.
| Command | Description |
|---|---|
| async default routing | Enables the router to pass routing updates to other routers over the AUX port configured as an asynchronous interface. |
| async dynamic address | Specifies dynamic asynchronous addressing versus default addressing. |
| ip tcp header-compression | Enables TCP header compression. |
