Hi all,
I have multicast question which drive me crazy.
The scenario is as follows,
R4-s0.1--(FR)----s0.1--R3-s1------s0-R2
|
s0.2
|\
| \
(FR)
| \
s0 s0
R5 R6
R4 s0.1 is frame subinterface point-to-point
R4 s0.2 is frame multpoint
IP connectivity is fine.
At R2
IP igmp join 224.2.2.2 at serial 0
I applied
R2 s0, ---- ip pim spare-mode
R3 s1 =ip pim spare-mode, s0.1 = ip pim spare-mode + ip pim nbma-mode
R4 s0.1,s0.2 = ip pim spare-mode + ip pim nbma-mode
R5 s0 = ip pim spare-mode + ip pim nbma-mode
R6 s0 = ip pim spare-mode + ip pim nbma-mode
I add ip pim send-auto-announce s0.1 scope 15 at R3
and
add ip pim send-auto-discovery s 0.2 scope 15 at R4
but I am unable to make ping 224.2.2.2 from R6, R5
I manage to work out with static RP but I couln't work out with AUTO-RP
Anyone have any idea ??
Regards,
David Ham
