Configuring Multicast VLAN Registration (CLI Procedure)
Multicast VLAN registration (MVR) allows hosts that are not part of a multicast source
VLAN (MVLAN) to still receive multicast streams from the MVLAN, allowing an MVLAN
to be shared across a Layer 2 network. Hosts remain in their own VLANs for bandwidth
and security reasons but are able to receive multicast streams from the MVLAN.
You can configure one or more VLANs on a switch to be MVLANs or MVR receiver VLANs.
By default, MVR is not configured on EX Series switches.
NOTE:
MVR is supported on VLANs running IGMP version 2 (IGMPv2) only.
NOTE:
When configuring MVR, the following restrictions apply:
•
You cannot enable multicast protocols on VLAN interfaces that are
members of MVLANs.
•
If you configure an MVLAN in proxy mode, IGMP snooping proxy mode will
be automatically enabled on all MVR receiver VLANs of this MVLAN. If a
VLAN is an MVR receiver VLAN for multiple MVLANs, all of the MVLANs
must have proxy mode enabled or all must have proxy mode disabled. You
can enable proxy mode only on VLANs that are configured as MVR source
VLANs and that are not configured for Q-in-Q tunneling.
•
After you configure a VLAN as an MVLAN, that VLAN is no longer available
for other uses.
To configure MVR:
1.
Configure the VLAN named
mv0
to be an MVLAN:
[edit protocols]
user@switch#
set igmp-snooping vlan mv0
data-forwarding
source groups
225.10.0.0/16
2.
Configure the MVLAN
mv0
to be a proxy VLAN:
[edit protocols]
user@switch#
set igmp-snooping vlan mv0
proxy
source–address 10.0.0.1
3.
Configure the VLAN named
v2
to be an MVR receiver VLAN:
[edit protocols]
user@switch#
set igmp-snooping vlan v2 data-forwarding
receiver
source-vlans mv0
4.
Install forwarding entries in the MVR receiver VLAN:
[edit protocols]
user@switch#
set igmp-snooping vlan mv0 data-forwarding receiver
install
