routerSendUnsolRaDefault - verify a host sending valid RSs
routerSendUnsolRaDefault.seq [-tooloption ...] -p routerSendUnsolRaDefault.def
routerSendUnsolRaDefault verifies that a NUT send valid RSs by the roules.
- A host sends valid RSs whose interval is MAX_INITIAL_RTR_ADVERT_INTERVAL(16 sec).
- A host sends the RSs at the most MAX_INITIAL_RTR_ADVERTISEMENTS (3) times.
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 between RAs is MAX_INITIAL_RTR_ADVERT_INTERVAL(16 sec). Because MinRtrAdvInterval(600*0.33 sec) is greater than MAX_INITIAL_RTR_ADVERT_INTERVAL(16 sec).
3. NUT throws the RAs at the most MAX_INITIAL_RTR_ADVERTISEMENTS (3) times.
6.2.4. Sending Unsolicited Router Advertisements
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.
