Hi,folks:
This is a question about multicast.
This is my topology.
R1(e0)--------------(e0)R2(s0)--------------------(s0)R3(e0)---
These interfaces configurated in sparse-dense-mose.
R1:e0 and lo0
R2:e0 and s0
R3:s0
R1 is auto-rp candicate and bsr for group 224.1.1.1
and now i ping 224.1.1.1 on R2, it's OK.
but when i ping the group on R3,it shows timeout.
when i add "ip pim sparse-dense-mode" command to the e0 interface of
R3,there is a log message:
*Mar 2 19:55:46.007: %PIM-5-DRCHG: DR change from neighbor 0.0.0.0 to
150.1.8.1
on interface Ethernet0/0
and then ping the group,it works.
That's why? it seems strange.
can somebody clarify this occurrence for me?
Thanks in advance for your help.
David
