Feature Configuration for Outer Header IE
The SMF enables Dual stack support in the UPF profile. When the dual stack is configured, the Outer Header Removal Description field in the Outer Header Removal IE is set to 6 to remove the GTP-U or UDP or IP header for IPv4 and IPv6 addresses.
To enable the dual stack support, use the following sample configuration:
config
profile network-element upf upf_profile_name
dual-stack-transport { true | false }
end
NOTES:
-
dual-stack-transport { true | false } : Enable or disable the dual stack transport for N3 tunnel.
When the dual-stack-transport true command is configured, the SMF sends the Outer Header Removal IE with the value 6 for IPv6 support on N3 interface.
