used.
The keyword optionally specifies the maximum TTL value in the VPLS echo request packet. The
ttl
TTL value in the VC-FEC label is decremented along the path at each VPLS node. When the TTL value
in the VC-FEC label reaches zero, the packet not forwarded but is redirected to the control plane for
additional processing. When the TTL value specified by the max_ttl_value parameter is exceeded, the
command ends. The valid max_ttl_value range is one to 30 with a default value of 4.
