I've a multicast network for security cameras (multiple RPs, bsr, connectivity with OSPF). The problem is that the monitors sometimes stop receiving the video stream.
(10.0.0.1, 18.104.22.168), 00:10:11/00:00:24, flags: T Incoming interface: Vlan1, RPF nbr 10.0.1.1, RPF-MFD Outgoing interface list: GigabitEthernet0/0, Forward/Sparse, 00:10:11/00:03:24, H
I noticed that after the "expire" timer counts down and the Outgoing interface changes to "null". Soon after that the route disappears from "sho ip mroute".
Could you get me some info how this should work? In test environment the counter restarts before reach 2:30. Moreover, when I remove the IGMP join-group the "show ip mroute" entries immediately goes to "null" outgoing interface.
I'm wondering what is responsible for resetting expire counter.
Thanks in advance!
