Syntax Description

vlan-name Specifies a VLAN name.
policy-name Specifies a policy file.


The default address range is (all multicast addresses), but excluding (the multicast control range).

Usage Guidelines

If no policy file is specified (the none option), the entire multicast address range, except for the multicast control range 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 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 ;
	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
