VLAN context command

This command is performed when in VLAN context mode. When a query occurs on the upstream
interface, an IGMP join is sent for all multicast addresses that are currently joined on the downstream
interface.
Syntax:
[no] igmp-proxy <domain-name>
Tells the VLAN which IGMP proxy domains to use with joins on the VLAN.
The no version of the command with no domain name specified removes all domains
associated with this VLAN.
Note that multiple different domains may be configured in the same VLAN context
where the VLAN is considered the downstream interface. The domain name must
exist prior to using this command to add the domain.
NOTE:
specified VLAN, no proxy IGMP would occur, that is, a proxy is not sent back out
on the VLAN that the IGMP join came in on.
If no unicast route exists to the border router, no proxy IGMP packets are sent.
