routerSendUnsolRaDefault2 - verify a host sending valid RSs
routerSendUnsolRaDefault2.seq [-tooloption ...] -p routerSendUnsolRaDefault2.def
routerSendUnsolRaDefault2 verifies that a NUT send valid RAs by the roules. The interval of RAs is between 7 sec. and 10 sec.
1. NUT throw valid RAs: - whoes parametser are as same as those. - that may contain a source link-layer optoin. - that may contain a MTU option. - that may contain a Prefix optoin.
2. The interval of RAs is between 7 sec. and 10 sec.
6.2.4. Sending Unsolicited Router Advertisements
Unsolicited Router Advertisements are not strictly periodic: the interval between subsequent transmissions is randomized to reduce the probability of synchronization with the advertisements from other routers on the same link [SYNC]. Each advertising interface has its own timer. Whenever a multicast advertisement is sent from an interface, the timer is reset to a uniformly-distributed random value between the interface's configured MinRtrAdvInterval and MaxRtrAdvInterval; expiration of the timer causes the next advertisement to be sent and a new random value to be chosen.
For the first few advertisements (up to MAX_INITIAL_RTR_ADVERTISEMENTS) sent from an interface when it becomes an advertising interface, if the randomly chosen interval is greater than MAX_INITIAL_RTR_ADVERT_INTERVAL, the timer SHOULD be set to MAX_INITIAL_RTR_ADVERT_INTERVAL instead. Using a smaller interval for the initial advertisements increases the likelihood of a router being discovered quickly when it first becomes available, in the presence of possible packet loss.
