Hierarchy Level


Specify the control-channel types for MPLS-TP mode. By default, LSPING (0x0008) is used, and the GACH-TLV is used along with this channel type.

As per RFC 7026, GACH-TLV is deprecated for ipv4 and on-demand-cv channel types.



Channel type 0x0021. This channel type uses the IP/UDP encapsulation and provides interoperability support with other vendor devices using IP addressing.


Channel type 0x0025. This is a new pseudowire channel type and is used for on-demand CV without IP/UDP encapsulation, where IP addressing is not available or non-IP encapsulation is preferred.
