The multicast boundary specifies subnets where the source traffic entering an interface is filtered to prevent the creation of mroute states on the interface. The multicast boundary can be specified through one standard ACL. However, when providing multicast services via a range of groups per service, an interface could potentially join arbitrary groups and, hence, need arbitrary combinations of ACL rules.

The Media Controller Service provides a deterministic high performance service with an easy to use API interface to manage and monitor real-time broadcast workflows in IP networks. It allows fast programming of static multicast routes and igmp snooping across L2/L3 interfaces with real-time tallies for feedback.

In network deployments, where border leaf or Superspine act as PEG and it is in the transit path to other multicast VTEPs, the multicast stream will not pass since the border leaf will decapsulate the packet even if it doesn't have a receiver. This transit node is called the Bud Node. The device should be able to send decapsulated packets to any local receivers as well as send the encapsulated packets to other VTEPs.

EOS currently supports EVPN Multicast by setting up PIM tunnels in the underlay with VXLAN as the transport. While this is an efficient delivery mechanism, it requires PIM to be deployed in the underlay. In certain cases, the overheads of provisioning/maintaining the multicast routers and the multicast routing state in the underlay may be significant. To support such scenarios, Ingress Replication (IR) or Head-End Replication (HER) can be used in the underlay to distribute overlay multicast traffic.

The ip address virtual command is generally used to conserve IP addresses in VXLAN deployments and can be used to provide an Anycast gateway. On a VLAN, the same IP address can be configured using this command on multiple VTEPS or on both MLAG devices. Release 4.22.1F introduced [ip address virtual support for PIM and IGMP]. Using that solution, users are required to configure pim ipv4 local-interface on the VLAN interface. PIM and IGMP then borrow the IP address from the local interface specified. Using this configuration, IGMP skips subnet checks for received control messages.
