hoplimit Parameter (IPv6)

Description

Sets the value of the hop limit in the IPv6 header for the outbound ICMPv6 error and reply packets. The hop limit defines the maximum number of routers a packet can pass through on the path to the destination. It is primarily used to clear messages from the network when a misconfiguration would otherwise case messages to endlessly loop through the same set of routers.

The hoplimit set on outbound ICMP requests and on UDP, TCP, and SCTP messages is not controlled by this property. It is instead controlled by the _ipv6_hoplimit property for each respective protocol.
