[Enterprise Switch] How to deploy MVR(Multicast VLAN Registration).. Follow

MVR (Multicast VLAN Registration)

MVR allows a subscriber on different VLAN to subscribe and unsubscribe to a multicast stream on the multicast VLAN.

Support models

ECS4100 series, ECS4120 series, ECS4620 series, etc.

Application

Multicast VLAN can be used to transmit multicast traffic (such as television channels) across a service provider’s network. Any multicast traffic entering an MVR VLAN is sent to all subscribers even on different VLANs. This can significantly reduce to process overhead required to dynamically monitor and establish the distribution tree for a normal IGMP VLAN.

Topology:

MVR Configuration example:

Create VLAN database for both normal VLAN and MVR VLAN

Create VLAN for normal VLAN and MVR VLAN:

Console(config)#vlan database

Console(config-vlan)#vlan 100,200,300,400,4000

Console(config-vlan)#exit

Normal VLAN Configure for different interfaces

Console(config)#interface ethernet 1/1

Console(config-if)#switchport allowed vlan add 100 untagged

Console(config-if)#switchport native vlan 100

Console(config-if)#exit

Console(config)#interface ethernet 1/2

Console(config-if)#switchport allowed vlan add 200 untagged

Console(config-if)#switchport native vlan 200

Console(config-if)#exit

Console(config)#interface ethernet 1/11

Console(config-if)#switchport allowed vlan add 300 untagged

Console(config-if)#switchport native vlan 300

Console(config-if)#exit

Console(config)#interface ethernet 1/12

Console(config-if)#switchport allowed vlan add 400 untagged

Console(config-if)#switchport native vlan 400

Console(config-if)#exit

Add Source port as MVR tagged member

Console(config)#interface ethernet 1/23

Console(config-if)#switchport allowed vlan add 4000 tagged

Console(config-if)#exit

Configure MVR profile

Console#config

Console(config)#mvr profile IPTV 225.77.22.0 225.77.22.255

Console(config)#mvr profile IPTV 225.77.32.0 225.77.32.255

Configure MVR domain

Console(config)#mvr domain 1

Console(config)#mvr domain 1 vlan 4000

Console(config)#mvr domain 1 associated-profile IPTV

Configures access port associate to the MVR domain

Console(config)#interface ethernet 1/1,2,11,12

Console(config-if)#mvr domain 1 type receiver

Console(config-if)#exit

Console(config)#interface ethernet 1/23

Console(config-if)#mvr domain 1 type source

Check MVR profile configuration

Console#show mvr profile

 MVR Profile Name      Start IP Addr.  End IP Addr.

 --------------------- --------------- ---------------

 IPTV                  225.77.22.0     225.77.22.255

                       225.77.32.0     225.77.32.255

Check MVR domain configuration

Console#show mvr domain 1

 MVR Domain                     : 1

 MVR Config Status              : Enabled

 MVR Running Status             : Active

 MVR Multicast VLAN             : 4000

 MVR Current Learned Groups     : 0

 MVR Upstream Source IP         : 0.0.0.0

Check MVR interface configuration

Console#show mvr interface

 MVR Domain : 1

 Flag: H - immediate leave by host ip

 Port     Type     Status              Immediate     Static Group Address

 -------- -------- ------------------- ------------- -------------------------

 Eth 1/23 Source   Active/Forwarding

 Eth 1/ 1 Receiver Active/Forwarding   Disabled

 Eth 1/ 2 Receiver Active/Forwarding   Disabled

 Eth 1/11 Receiver Active/Forwarding   Disabled

 Eth 1/12 Receiver Active/Forwarding   Disabled

When multicast hosts join on MVR receiver ports and the multicast groups conform to the MVR profile configuration, it will join on MVR VLAN as member ports. And then the multicast host could receive the multicast stream from MVR source ports.

Console#show mvr members

 MVR Domain : 1

 MVR Forwarding Entry Count :4

 Flag: S - Source port, R - Receiver port.

       H - Host counts (number of hosts joined to group on this port).

       P - Port counts (number of forwarding ports).

 Up time: Group elapsed time (d:h:m:s).

 Expire : Group remaining time (m:s).




 Group Address   VLAN Port        Up time     Expire Count
