Syntax

[ no ] ip source-prefix ipAddress ipAddressMask deny

Release Information

Command introduced before JunosE Release 7.1.0.

Description

Configures a subscriber interface or a primary IP interface that is enabled for dynamic creation of subscriber interfaces to demultiplex traffic with the specified IP address and mask. On the ERX1440 router or the E320 router, you can configure up to 1024 subnets for static subscriber interfaces per primary IP interface when each subnet has a variable network mask that is less than /32. The number of subnets identifying a single route (/32) is still limited by the global maximum of 16,000 hosts per line module. The no version removes the association between the interface and the specified IP address and mask.

Options

• ipAddress—IP address of the physical interface that receives messages for this subscriber
• ipAddressMask—Network mask for associated IP subnet
• deny—Filters packets matching this command
