Redirect is a read-only Counter32 counting the number of Re-Direct report frames recorded for this IP-to-IP conversation; a value of 4294967294 means the count is unknown rather than a genuine zero. This counter matters to an admin because it isolates a router telling a host that a better next-hop exists for a destination, which can indicate a suboptimal routing table on the host, letting them see that specific condition trending up without having to sift through every ICMP message the host or pair exchanged. If Redirect for the pair 10.4.12.30 and 198.51.100.7 starts climbing while other ICMP counters in the same row stay flat, that isolated rise points specifically at a router telling a host that a better next-hop exists for a destination, which can indicate a suboptimal routing table on the host rather than a general ICMP flood.
