I have problem with Nexus 3064. I would like to send statically multicast to Cisco 3550 switch.
I configured PIM router both on Nexus and 3550 switch.
n3k (sender)
interface Vlan2241
ip address 172.29.0.13/30
ip pim sparse-mode
ip igmp static-oif 239.254.1.1 source 172.30.1.1
ip igmp static-oif 239.254.1.2 source 172.30.1.2
ip igmp static-oif 239.254.1.3 source 172.30.1.3
ip igmp static-oif 239.254.1.4 source 172.30.1.4
c3550 (receiver)
interface GigabitEthernet0/0.2241
encapsulation dot1Q 2241
ip address 172.29.0.14 255.255.255.252 ip pim sparse-mode
When checking mroute table on c3550 (receiver) – is ok, multicast arrives.

When the timeout counters end (here you can see 0:02:35) multicast doesn’t work, does not help anything - I have to disable and enable interface .
I expect, when I start send multicast it is going continuously, no matter if the client sends IGMP query or not.
