Virtual Private Dialup Network Commands

This chapter describes the function and displays the syntax for virtual private dialup network commands. For more information about defaults and usage guidelines, see the corresponding chapter of the Dial Solutions Command Reference.

clear vpdn tunnel

To shut down a specified tunnel and all the MIDs within it, use the clear vpdn tunnel EXEC command.

clear vpdn tunnel network-access-server gateway-name

network-access-server	Name of the network access server at the far end of the tunnel, probably the point of presence of the public data network or the Internet Service Provider's.
gateway-name	Host name of home gateway at the local end of the tunnel.

show vpdn

To display information about active Level 2 Forwarding (L2F) protocol tunnel and Level 2 Forwarding (L2F) message identifiers in a virtual private dialup network, use the show vpdn EXEC command.

show vpdn

vpdn domain-delimiter

To specify the characters to be use to delimit the domain prefix or domain suffix, use the vpdn domain-delimiter global configuration command.

vpdn domain-delimiter characters [suffix | prefix]

characters	One or more specific characters to be used as suffix or prefix delimiters. Available characters are %, -, @, \ , #, and /. If a backslash (\) is the last delimiter in the command line, enter it as a double backslash (\\).
suffix | prefix	Usage of the specified characters.

vpdn enable

To enable virtual private dialup networking on the router and inform the router to look for tunnel definitions in a local database and on a remote authorization server (home gateway), if one is present, use the vpdn enable global configuration command.

vpdn enable

vpdn force-local-chap

To cause the home gateway to issue its own CHAP challenge even if one has already been issued from the network access server, use the vpdn force-local-chap global configuration command. To disable the home gateway's issuing its own CHAP challenge, use the no form of this command.

vpdn force-local-chap
no vpdn force-local-chap

vpdn incoming

To specify the local name to use for authenticating and the virtual template to use for building interfaces for incoming connections when a Level 2 Forwarding (tunnel) connection is requested from a certain remote host, use the vpdn incoming global configuration command.

vpdn incoming remote-name local-name virtual-template number

remote-name	Case-sensitive name of the remote host requesting the connection.
local-name	Case-sensitive local name to use when authenticating back to the remote host.
virtual-template number	Virtual template to use for building interfaces for incoming calls.

vpdn local-authentication

To enable local authentication of users on the network access server before the connection is forwarded to the home gateway, use the vpdn local-authentication global configuration command. To reset the network access server to the default in which local authentication is disabled, use the no form of this command.

vpdn local-authentication
no vpdn local-authentication

vpdn outgoing

To specify use of Dialed Number Information Service (DNIS) or use of a domain name when selecting a tunnel for forwarding traffic to the remote host (the home gateway) on a virtual private dialup network, use the vpdn outgoing global configuration command.

vpdn outgoing {dnis dialed-number | domain-name} local-name ip ip-address

dnis dialed-number	Dialed number to be used for selecting a specific tunnel to be used for forwarding traffic to a home gateway.
domain-name	Case-sensitive name of the domain to forward traffic to.
local-name	Case-sensitive local name to use when authenticating the tunnel to the remote host.
ip ip-address	IP address of the remote host (home gateway).

vpdn search-order

To specify how the service provider's network access server is to perform VPDN tunnel authorization searches, use the vpdn search-order global configuration command. To remove a prior specification, use the no form of the command.

vpdn search-order {dnis domain | domain dnis | domain | dnis}
no vpdn search-order

dnis domain	Search first on the Dialed Number Information Service (DNIS) information provided on ISDN lines and then search on the domain name.
domain dnis	Search first on the domain name and then search on the DNIS information.
domain	Search on the domain name only.
dnis	Search on the DNIS information only.

vpdn source-ip

To set the source IP address of the network access server, use the vpdn source-ip global configuration command.

vpdn source-ip address

address

IP address of the network access server.
