As with LCP monitoring or ICMP polling for IPv4, ICMPv6 polling regularly sends requests to a remote peer. Ping commands are transmitted and the answers to them are monitored. Unlike LCP monitoring, the target site for ICMPv6 pings can be freely defined. Pinging a router in a remote network thus provides monitoring for the entire connection and not just the section to the Internet provider.
A ping interval is defined for the remote site in the IPv6 polling table. Further, for the event that replies are missed, the number of retries before the transmission of a new LCP request is defined. Should the transmitter not receive any reply to the retries, the target for the ping requests is classified as unavailable.
Up to four different IPv6 addresses can be entered for each remote site that will be checked in the remote network in parallel. Only if all of the IPv6 addresses are unavailable is the connection considered to have failed.
The settings for ICMPv6 polling in LANconfig can be found in the configuration section .
- Remote site
- Here you select the name of a remote site from the list of remote sites.
- IPv6 address 1- 4
- Enter here up to 4 IPv6 addresses, which are pinged one after the other in order to check the connection for this peer. The connection is considered to be intact even if just one of the specified IPv6 addresses can be reached. Be sure to choose IPv6 addresses that can be reached reliably to avoid unnecessary backup connections being initiated. If you set all four IPv6 addresses as "::", the DNS server that is pinged is the one assigned via DHCPv6 or router advertisement.
- Ping interval
- Enter the ping interval in seconds here.
Note: If you enter 0 both here and for retries, a default interval of 20 seconds and 5 repetitions is used.
- Retries
- Enter the number of tries each second if no response is received to a ping. If the repeated pings also go unanswered, the connection is terminated.
Note: If you enter 0 both here and ping interval, a default interval of 20 seconds and 5 repetitions is used.
- Source address (optional)
- This is where you can configure an optional sender address to be used instead of the one that would normally be selected automatically for this target address.
