I have attached a network diagram explaining IPTV network , i have below queries to understand & configure IPTV .
- All ports on edge switches are configured as access ports in VLAN 101.
- On Core & L-2 switches , configuration is simple (i.e) VLAN , VLAN IP address , Access ports & basic administration configuration.
- DCM switch is converting analog signal from head end to IP.
Recently added 50 IPTVs as expansion , due to which flickering/latentcy - mainly BW related issue were seen. As a recommendation from vendor , Multicast needs to be enabled.I have tried understanding L-2 Multicast on cisco portal , however unable to understand what needs to configured on Cisco Core & Edge.
- What can be the recommendation for implementation for IP/layer-2 Multicast?
- What is IGMP snooping & IGMP querier?
- What does ip igmp snooping querier & ip igmp snooping command ?
Thanks in advance
