Understanding GGSN Redirection

Junos OS supports GPRS tunneling protocol (GTP) traffic and gateway GPRS support node (GGSN) redirection. A GGSN (X) can send create-pdp-context responses in which it can specify different GGSN IP addresses (GGSN Y and GGSN Z) for subsequent GTP-C and GTP-U messages. Consequently, the SGSN sends the subsequent GGSN tunneling protocol, control (GTP-C) and GGSN tunneling protocol, user plane (GTP-U) messages to GGSNs Y and Z, instead of X.
