Designating Upstream Interface
To specify the upstream interface for IGMP proxy operation, use the following command.
Command
Mode
Description
ip igmp proxy-service
Interface
[VLAN]
Designates the upstream interfaces of mroute proxy.
no ip igmp proxy-service
Releases the upstream interface of mroute proxy.

Configuring Upstream Interface Mode
When a single downstream interface is specified with multiple upstream interfaces, V8102
supports two methods of IGMP proxy operation that are priority mode and load balancing
mode. You can choose the way how to handle multicast traffic going to upstream interfac-
es. The priority mode is configured by default.
There are two modes for handling the multicast traffic toward upstream interfaces
- Priority mode: Each downstream interface joins one upstream interface of the highest
priority based on its credit, priority and vid.
- Load balancing mode: It distributes multicast packets across multiple links of upstream
interfaces with the largest credit value according to hash-threshold algorithm for IGMP
group.
Every upstream interface has a credit unit value (default :100) and a priority. The up-
stream interfaces are specified a priority based on its credit value, the configured priority
value and vid. The highest upstream interface has larger credit, higher priority and lower
vid than other ones.
To specify the priority on an upstream interface, use the following command.
Command
Mode
Description
ip igmp proxy-service priority
<0-255>
Interface
[VLAN]
Specifies the priority on an upstream interface (de-
fault :0)
no ip igmp proxy-service priori-
ty
Deletes the configured priority of upstream interface.
To choose the upstream interface mode for IGMP proxy operation, use the following
command.
Command
Mode
Description
ip igmp proxy-service multipath
grpip
Global
Specifies load balancing mode for upstream interface
no ip igmp proxy-service multi-
path grpip
Specifies priority mode for upstream interface.
