(usagi-users 02281) Re: why a IPv6 host keep sending RS packet to all-router multicast ad dress?

["IDA Hiromu" <hider@xxxxxxxxxxxxxxxxx>]

Hi, Michael.

| About every 10 seconds, it will send a RS packet to the muliticast address
| of all-router.  Could anybody give me a hint why it is trying to do so?

    Don't you enable MobileIPv6 on kernel configuration of your host ?
    * If you don't use, following has no relation. Excuse me.

    Is your router's MaxRtrAdvInterval number less than or equal to 5 ?
    * check /etc/radvd.conf ( I use RedHat 7.3 )

    Default RS packet polling time of host(MN) is 5(DEF_RTR_POLL_IVAL), 
    so if Router Advertisement slightly delayed, MN would send RS again.

    Change MaxRtrAdvInterval to short, or MN's default polling time to long. 
    (DEF_RTR_POLL_IVAL in usagi/kernel/linux24/net/ipv6/mobile_ip6/mdetect.c )
