Configuring Static Multicast ARP

Configuration Example

1. Configure the static multicast FDB entry.
2. Configure the static multicast ARP entry:

CN4093 Application Guide for N/OS 8.4
To configure multicast MAC ARP, you must perform the following steps:
 Configure the static multicast forwarding database (FDB) entry: Since there is no
port list specified for static multicast ARP, and the associated MAC address is
multicast, you must specify a static multicast FDB entry for the cluster MAC
address to limit the multicast domain. If there is no static multicast FDB entry
defined for the cluster MAC address, traffic will not be forwarded. Use the
following command:
CN 4093(config)# mac-address-table multicast <cluster MAC address> <port(s)>
Configure the static multicast ARP entry: Multicast ARP static entries should be

configured without specifying the list of ports to be used. Use the following
command:
CN 4093(config)# ip arp <destination unicast IP address> <destination multicast MAC
address> vlan <cluster VLAN number>
Consider the following example:
Cluster unicast IP address: 10.10.10.42

 Cluster multicast MAC address: 03:bf:0a:0a:0a:2a
Cluster VLAN: 42

 List of individual or port LAGs to which traffic should be forwarded: 54 and 56
Following are the steps to configure the static multicast ARP based on the given
example:
CN 4093(config)# mac-address-table multicast 03:bf:0a:0a:0a:2a 42 54,56
CN 4093(config)# ip arp 10.10.10.42 03:bf:0a:0a:0a:2a vlan 42
You can verify the configuration using the following commands:
 Verify static multicast FDB entry:
CN 4093(config)# show mac-address-table multicast address
03:bf:0a:0a:0a:2a
