Huawei quidway s7700 - Configuring IGMP Snooping; Establishing the Configuration Task

l Controlling multicast service accurately
l Ensuring the service quality for most VoD users
l Reducing the impact of multicast attack
2.3 Configuring IGMP Snooping
This section describes how to configure IGMP snooping in a VLAN.
2.3.1 Establishing the Configuration Task
Applicable Environment
VLAN-based IGMP snooping runs on the S7700 between an upstream router and hosts. The
S7700 monitors the multicast protocol packets exchanged between the router and hosts to
maintain the forwarding entries for the multicast packets. In this manner, the S7700 manages
and controls forwarding of multicast data packets to implement Layer 2 multicast.
Pre-configuration Tasks
Before configuring IGMP snooping in a VLAN, complete the following tasks:
l Connecting interfaces and configuring the physical parameters of each interface to make
the physical layer in Up state
l Creating a VLAN
l Adding interfaces to the VLAN
Data Preparation
To configure IGMP snooping in a VLAN, you need the following data.
No.
Data
1 ID of the VLAN
2 (Optional) Version of IGMP messages
3 Types and numbers of interfaces
4 (Optional) Parameters of a querier: interval
for sending IGMP General Query messages,
robustness variable, maximum response time,
and interval for sending Last Member Query
messages
5 (Optional) ACL rules applied to a multicast
policy
6 (Optional) Suppression duration of IGMP
messages
7 (Optional) Aging time of the router interface
