Understanding R6 Information Elements Removal

The Third–Generation Partnership Project (3GPP) R6 information element (IE) removal feature allows you to retain interoperability in roaming between Second–Generation Partnership Project (2GPP) and 3GPP networks. You can configure the GPRS tunneling protocol (GTP)-aware Juniper Networks device, residing on the border of a public land mobile network (PLMN) and a GPRS Roaming Exchange (GRX) and acting as a Gp firewall, to remove 3GPP-specific attributes from the GTP packet header when the packet passes into a 2GPP network. You can configure the device to remove the RAT, RAI, ULI, IMEI-SV, and access point name (APN) restriction IEs from GTP messages prior to forwarding these messages to the gateway GPRS support node (GGSN).
