ICMP Attacks - InfoSec ResourcesThe ICMP router discovery messages are called “Router Advertisements” or “Router Solicitations”. The router discovery message is not a routing protocol. It enables hosts to discover the existence of a neighbouring routers, but not which router is best to reach a particular destination. Router advertisement is an ICMP message (type 9, code 0) with an advertisement lifetime.Sun, 11 Mar 2018 23:59:00 GMT
Entry in Router Log - Plusnet CommunityYour router will only be expecting to receive ICMP destination unreachable packets that correspond to previous outgoing packets, and only for a limited time after the outgoing connection attempt.
