MVR multicast protocol layer 2

22 Maj 2017 Dodaj komentarz

Multicast VLAN Registration protocol in Cisco switches deliver multicast packets received from a source VLAN to destination VLAN. Multicast routing has to be disabled when MVR is enabled. Multicast traffic can be delivered to the source VLAN by a port. This port can be work in trunk or access mode. Multicast traffic will be received from destination VLAN by a port or ports. These ports have to works in access mode only. These ports call subscribers ports.
When we want to configure MVR in a switch we have to configure in global configuration and in subscribers ports.
In the global configuration, we set up source VLAN and a  multicast group which will be transferred do the destination VLAN to the subscriber’s ports.

mvr vlan 611
mvr
mvr querytime 10
mvr mode dynamic
mvr group 232.0.2.10
mvr group 232.40.10.8
mvr group 239.40.10.8

In subscriber’s ports are configured multicast groups which we needed receive.

interface FastEthernet0/24
 switchport access vlan 621
 switchport mode access
 mvr type receiver
 mvr vlan 611 group 232.0.2.10
 mvr vlan 611 group 232.40.10.8
 mvr vlan 611 group 239.40.10.8
 mvr immediate
Parallel to the MVR protocol can work properly IGMP protocol.

ip igmp snooping vlan 621 static 0100.5e00.020a interface Fa0/24
ip igmp snooping vlan 621 static 0100.5e28.0a08 interface Fa0/24

or

ip igmp snooping vlan 621 static 232.0.2.10 interface Fa0/24
ip igmp snooping vlan 621 static 232.40.10.8 interface Fa0/24
ip igmp snooping vlan 621 static 239.40.10.8 interface Fa0/24
