Example: IGMP Dynamic Profile

[ Contents] [ Prev] [ Next] [ Index] [ Report an Error]

In this example, IGMP is configured for subscriber access using user-defined variables and JUNOS internal variables.

The user-defined variables equate to RADIUS settings as follows:

User-Defined Variable Name	JUNOS Variable	RADIUS VSA Name	RADIUS Attribute Number	RADIUS Setting
var-igmp-version	$var-igmp-version	IGMP-Version	26–78	3
var-igmp-access-grp	$var-igmp-access-grp	IGMP-Access-Group-Name	26–71	"reject_igmp_225"
var-igmp-access-src-grp	$var-igmp-access-src-grp	IGMP-Access-Source- Group-Name	26–72	"reject_igmp_115"
