MULTICAST issue

[annirajput]

Hi 

Can any one tell me how I can disable fast switching on ISR4331-DC/K9.

I am facing issue multicast packets dropped 

(10.71.6.246, 239.255.255.253), 00:02:03/00:00:56, flags: T
Incoming interface: Vlan100, RPF nbr 10.70.126.1
Outgoing interface list:
GigabitEthernet0/0/0, Forward/Dense, 00:02:03/stopped
GigabitEthernet0/0/1, Forward/Dense, 00:02:03/stopped
Vlan700, Prune/Dense, 00:02:03/00:00:56

yes dense mode enabled

Hello
Check your receiving hosts, make sure there are open to receive MC if so , test the routing path from MC receiver to MC source, do you have reachability 

Also on the HSRP group for the rtrs which participate in MC pim, you could manually set the DR for the
subnet, if priority’s are the same (defaults set to 1) highest ip address wins election

primary
atandby 1 ip 10.70.101.1
standby 1 priority 110
standby 1 name DATA1
ip pim redundancy DATA1 dr-priority priority 255

secondary
standby 1 ip 10.70.101.x
standby 1 priority <lower than 110>
standby 1 name DATA1

Scratch the above, just realised your using igmpv3-apologies

Hello
Yes i have, which suggest those interfaces have stop receiving any membership request for any MC group.

Do you have a topology of your network.
