 VPP1 is configured with "End.M.GTP6.D.Di", and VPP4 is configured with "End.M.GTP4.E". Others are configured with "End". The packet generator sends a GTP-U packet over UDP/IPv6 toward D:: of the packet capture. VPP1 translates it to SRv6 toward D:: with SR policy <D2::, D3::, D4::TEID> in SRH. VPP4 translates the SRv6 packet to the original GTP-U packet and send out to the packet capture.
