■ Detect group view
Description The router probes the IP addresses in a detect group in the ascending order of their
assigned sequence numbers and determines whether the detect group is reachable as
follows:
■ When the relationship between the IP addresses is logical AND, the detect group is
regarded reachable only if all IP addresses can be pinged. If the router fails to ping
an IP address, it stops probing and considers that the detect group is unreachable.
■ When the relationship between the IP addresses is logical OR, the detect group is
regarded reachable if one of the IP addresses can be pinged. When an IP address is
pinged, the router stops probing and considers that the detect group is reachable.
