show evpn multicast-snooping assisted-replication next-hops

Syntax

Description

Display next-hop information on an assisted replication (AR) leaf device that the AR leaf uses for load-balancing among available AR replicators.

  • AR leaf devices in the QFX5000 line of switches perform load-balancing among the available AR replicators by designating a particular AR replicator device for a VLAN or VXLAN network identifier (VNI).

  • AR leaf devices in the QFX10000 line of switches load-balance among the available AR replicators actively based on traffic flow levels within a VNI.

An AR device will have an AR VXLAN encapsulation next hop and an ingress replication VXLAN encapsulation next hop towards a particular AR replicator. Load-balancing next hops are AR VXLAN encapsulation next hops towards the AR replicator.

Output for this command is only available when IGMP snooping is enabled.

Options

index nh-index

(Optional) Display information only for the specified next-hop.

instance evpn-instance-name

(Optional) Display information only for the specified EVPN instance.

Note:

You can only enable IGMP snooping for the default-switch EVPN instance on QFX Series switches in an EVPN-VXLAN environment, so you don’t need to use the instance option because this command only displays information for the default-switch instance.

l2-domain-id ID

(Optional) Display information only for the specified Layer 2 domain ID, which can be a VLAN ID, a VXLAN network identifier (VNI), or a service identifier (I-SID) within the range from 1 through 16777214.

Note:

For QFX Series switches in an EVPN-VXLAN environment, you must specify the Layer 2 domain ID as a VNI.

Table 1: show evpn multicast-snooping assisted-replication next-hops Output Fields

Field Name

Field Description

Instance

EVPN instance name.

VN Identifier

Lists AR load-balancing next-hop information about this VNI.

Load Balance Nexthop Index

Index of the load-balancing next hop (top level).

Load balance to

Lists next-hop information for available AR replicators.

Nexthop Index

AR next hop for the AR replicator in the AR IP output field.

Interface

AR tunnel interface name to this AR replicator.

AR IP

IP address of this AR replicator (the configured secondary loopback interface address for AR).

(Designated Node)

(AR leaf devices in the QFX5000 line of switches only) Designated AR replicator for a VLAN or VNI for load-balancing AR operation among the available AR replicators.

Note:

AR leaf devices in the QFX10000 line of switches load-balance among the available AR replicators based on traffic flow levels within a VNI, and don’t show a designated replicator in the output of this command.

Sample Output

show evpn multicast-snooping assisted-replication next-hops
