Configures the MVR address range on a VLAN.
| vlan-name | Specifies a VLAN name. |
| policy-name | Specifies a policy file. |
The default address range is 224.0.0.0/4 (all multicast addresses), but excluding 224.0.0.0/24 (the multicast control range).
If no policy file is specified (the none option), the entire multicast address range 224.0.0.0/4, except for the multicast control range 224.0.0.0/24 is used for MVR.
MVR must first be configured on the VLAN before using this command.
If the policy is later refreshed, groups denied and newly allowed groups in the policy are flushed from fast path forwarding. This allows synching existing channels with the new policy, without disturbing existing channels.
The following is a sample policy file mvrpol.pol. This policy configures 236.1.1.0/24 as the MVR address range. Any address outside this range has the standard switching behavior on an MVR VLAN.
Entry extreme1 {
if match any {
nlri 236.1.1.0/24 ;
}
then {
permit ;
}
}
The following example configures the MVR address range specified in the policy file mvrpol.pol for the VLAN v1:
configure mvr vlan v1 mvr-address mvrpol
This command was first available in ExtremeXOS 11.4.
This command is available on platforms that support the appropriate license. For complete information about software licensing, including how to obtain and upgrade your license and which licenses support the MVR feature, see the Switch Engine v33.1.1 Licensing Guide document.
