June 30, 2006

Format:

adc-avpair = "vpdn:tunnel-client-ip-address-=<tunnel client ip address>",

Example:

adc-avpair = "vpdn:tunnel-server-client-ip-address=192.168.3.5",

vpdn:nativeip sub-attribute

This attribute defines a session as a native IP pipe, meaning the session acts as a tunnel for native IP traffic. It is currently used for PPP sessions only. It may be activated dynamically, enabling the change of a connected PPP session Native IP status on the fly.

General:

 

Operation Mode:

Access-Accept message

 

Service-Accept message

Vendor-type:

85

Vendor-length =

2 + name length + 3

Format:

 

gcon-avpair = "vpdn:nativeip=<ppp>",

 

Example:

 

gcon-avpair = "vpdn:nativeip=ppp",

 

vpdn:ip-tunnel sub attribute

The vpdn:ip-tunnel sub attribute defines the tunneling protocol and the destination tunneling server IP address, which all the session data should be tunneled to. It may be activated dynamically, enabling to change the session tunneling protocol and destination on the fly. The attribute may be included once in access accept messages, and the system ignores all other instances.

General:

Operation Mode:

Access-Accept message

 

Service-Accept message

Vendor-type:

86

Vendor-length =

2 + 7-15 + attribute-name length

Format:

adc-avpair = "vpdn:ip-tunnel=<gre;IP address[,redundant IP address]ip-in-ip;IP address [,redundant IP address]>",

Example 1:

adc-avpair = "vpdn:ip-tunnel=gre;192.168.1.34",

Example 2:

adc-avpair = "vpdn:ip-tunnel=gre;192.168.1.34,192.168.4.1",
