Configuring IGMP Snooping over EVPN MPLS
IGMP snooping over EVPN MPLS can be configured to save bandwidth resources for EVPN networks that carry multicast traffic.
Usage Scenario
By default, when the EVPN function is deployed on a network to carry Layer 2 multicast services, multicast data packets are broadcast on the network. The devices that do not need to receive the multicast data packets also receive these packets, which wastes network bandwidth resources. To resolve this issue, deploy IGMP snooping over EVPN MPLS. After IGMP snooping over EVPN MPLS is deployed, IGMP snooping packets are transmitted on the network through EVPN routes, and multicast forwarding entries are generated on devices. Multicast data packets from a multicast source are advertised only to the devices that need these packets, saving network bandwidth resources.
Pre-configuration Tasks
Before configuring IGMP snooping over EVPN MPLS, complete the following task:
- Configuring IGMP Snooping and Proxy
- To implement IGMP snooping over EVPN MPLS, you must configure basic IGMP snooping and proxy functions.
- Configuring the Access Side
- You can configure IGMP snooping over EVPN MPLS on the access side of an EVPN that carries multicast services for various scenarios.
- Verifying the Configuration
- After configuring IGMP snooping over EVPN MPLS, verify the configuration.
