Configuring the number of SMET Nexthops
Junos OS uses EVPN route type 6, selective multicast Ethernet (SMET) route message to support the following:
External multicast sender (IGMP proxy)—EVPN route type 6 messages are used within the EVPN network. The ingress PE device translates the IGMP message to an EVPN route type 6 message and the egress PE device translates the EVPN route type 6 message back to an IGMP message.
Inter-VLAN multicast—EVPN type route 6 messages are used to create a PIM states on a PE device with an IRB interface. This allows multicast traffic to be sent across VLANs.
Selective multicast forwarding—The EVPN route type 6 messages are used to distribute the routing information indicating a PE device’s interest for a multicast group.
The information in the EVPN route type 6 message are used to
build a list of SMET next hops, which can be used to selectively replicate
and forward multicast packets. SMET next hop is a list of outgoing
interfaces (OIFs) identifying the interested PEs . Multicast groups
are mapped to SMET next hops. If multicast groups that have the same
set of interested PEs, they can share a SMET next hop. The number
of SMET nexthops defaults to 10,000 and can be increased by configuring
the smet-nexthop-limit option. When a device reaches
the SMET nexthop limit, the device will start using inclusive multicast
forwarding for multicast traffic.
Devices in the network that do not support snooping or cannot send EVPN route type 6 messages are always included in the SMET next hop. This ensures those devices that do not support EVPN type 6 messages will be able to receive multicast traffic.
To configure the number of SMET nexthops, you can use the following statement:
User@PE1# set forwarding-options multicast-replication
evpn smet-nexthop-limit nexthop range.
In some cases, you may want to bypass selective multicast forwarding and send multicast traffic to all devices. If you wish to send multicast traffic to a group, you can list the multicast group address with the following statement
User@PE1# set multicast-snooping-options flood-groups
[ip-addresses]
OSPF messages, which use multicast addresses for communication, are automatically included in the multicast snooping forwarding table.
