>Description:
These days I used freebsd5.3 to configure a ipv6 multicast network.
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:
