From: Papa Tana Injection-Date: Tue, 18 Aug 2020 06:58:41 +0000 Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Xref: csiph.com comp.protocols.misc:70 As stated here: # https://www.juniper.net/documentation/en_US/junos-mobility11.2/topics/con= cept/gtp-mobility-teid-allocation-overview.html GTP-C allocates a TEID to identify a set of endpoints for a GTP-C tunnel, a= s shown in Figure 1. For each bearer, a separate GTP-U tunnel with its own = TEID is established. My understanding of that is: TEID at GTP-C is used only at GTP-C side, and = they are just needed to identify the set of endpoints addressed to the GTP-= U side.
