Its topology is HostA(winxp) | FreeBsd5.3(MR,pim6sd RP) | | FreeBsd5.3(MR,pim6sd ) | | HostB(xp) //MR: ipv6 Multicast Router //routing software:zebra+ospf6d,pim6sd The problem is: when I run ipv6 multicast applications on HostA(as sender) and HostB(as recv),it seems to work OK .Through pim6sd's log I can see it really create groups, and HostB can recieve data. However ,after a while ,error occurs.The router which worked as RP is dead(Other routers works OK), and it gives an information as below: --error infomation--------------------------------------------------------------------- Sep 13 19:49:07 BSDR1 kernel: em1: Link is up 1000 Mbps Full Duplex Sep 13 19:49:29 BSDR1 kernel: em1: Link is Down Sep 13 19:49:31 BSDR1 kernel: em1: Link is up 1000 Mbps Full Duplex Sep 13 19:52:43 BSDR1 pim6sd[597]: receive_pim6_bootstrap: Bootstrap from an unrecognized neighbor (fe80::207:e9ff:fe10:5f8d) on em0 Sep 13 19:53:18 BSDR1 su: xcr to root on /dev/ttyp0 Sep 13 19:53:42 BSDR1 pim6sd[597]: receive_pim6_bootstrap: Bootstrap from an unrecognized neighbor (fe80::207:e9ff:fe10:5f8d) on em0 Sep 13 19:54:43 BSDR1 pim6sd[597]: receive_pim6_bootstrap: Bootstrap from an unrecognized neighbor (fe80::207:e9ff:fe10:5f8d) on em0 Sep 13 19:56:43 BSDR1 pim6sd[597]: receive_pim6_bootstrap: Bootstrap from an unrecognized neighbor (fe80::207:e9ff:fe10:5f8d) on em0 Sep 13 19:57:43 BSDR1 pim6sd[597]: receive_pim6_bootstrap: Bootstrap from an unrecognized neighbor (fe80::207:e9ff:fe10:5f8d) on em0 Sep 13 20:09:48 BSDR1 syslogd: kernel boot file is /boot/kernel/kernel Sep 13 20:09:48 BSDR1 kernel: Sep 13 20:09:48 BSDR1 kernel: Sep 13 20:09:48 BSDR1 kernel: Fatal trap 12: page fault while in kernel mode Sep 13 20:09:48 BSDR1 kernel: fault virtual address = 0x0 Sep 13 20:09:48 BSDR1 kernel: fault code = supervisor read, page not present Sep 13 20:09:48 BSDR1 kernel: instruction pointer = 0x8:0xc06bd98e Sep 13 20:09:48 BSDR1 kernel: stack pointer = 0x10:0xd53a4c60 Sep 13 20:09:48 BSDR1 kernel: frame pointer = 0x10:0xd53a4cc4 Sep 13 20:09:48 BSDR1 kernel: code segment = base 0x0, limit 0xfffff, type 0x1b Sep 13 20:09:48 BSDR1 kernel: = DPL 0, pres 1, def32 1, gran 1 Sep 13 20:09:48 BSDR1 kernel: processor eflags = interrupt enabled, resume, IOPL = 0 Sep 13 20:09:48 BSDR1 kernel: current process = 35 (swi1: net) Sep 13 20:09:48 BSDR1 kernel: trap number = 12 Sep 13 20:09:48 BSDR1 kernel: panic: page fault Sep 13 20:09:48 BSDR1 kernel: Uptime: 49m3s Sep 13 20:09:48 BSDR1 kernel: Cannot dump.
