Briefly describe the following ICMPv6 message types: Router Solicitation, Router Advertisement, and Redirect.
What will be an ideal response?
Router Solicitation (RS) (ICMPv6 type 133)-When an interface becomes active, a node may send a Router Solicitation message, asking any routers connected to the local link to identify themselves by sending their Router Advertisement messages immediately (rather than waiting for the next scheduled advertisement).
Router Advertisement (RA) (ICMPv6 type 134)-Routers periodically or upon request send out messages that contain at least one and possibly more of their own link-layer addresses, the network prefix for the local subnet, the Maximum Transmission Unit (MTU) for the local link, suggested hop limit values, and other parameters useful for nodes on the local link. Router Advertisement messages can also contain flagged parameters to indicate what type of address autoconfiguration process new nodes should use to join the network.
Redirect (ICMPv6 type 137)-When a router knows a better first-hop for a particular destination address (which could be off-link), it sends a Redirect message to the sender indicating that the sender should contact a different router to send subsequent packets.
