We would like to show you a description here but the site won’t allow us. 102. By default, the device responds to an Address Resolution Protocol (ARP) request only if the destination address of the ARP request is on the local network of the incoming interface. The example also configures the device to reply to ARP requests from the node using the publish option. When you specify the speed, all the interfaces that make up the aggregated Ethernet bundle have the same speed. Network switches cannot learn the NLB multicast MAC address in the course of their usual operations. In Junos OS, static routes have a global preference (administrative distance) of 5. There are many practical applications for static routes. Jan 15, 2025 · To support this configuration, you must configure the network infrastructure to use static ARP entries and MAC address table entries. 1/24) and the corresponding MAC address of a node on the same Ethernet subnet (00:ff:85:7f:78:03).

Note: The fields that support configuration through site variable have a help text showing the site variable configuration format underneath them. MX Series routers support the show bridge mac-table command in place of this command. Specify the link speed for the aggregated Ethernet links. See link-speed (Aggregated Ethernet). Static routing is often used at the network edge to support attachment to stub networks. If you skip the manual configuration step, the network switches may flood NLB traffic to all ports or drop packets. The entry consists of the interface’s IP address (10. 1X authentication. This command installs a permanent entry in the ARP table of the router, while dynamically learned entries are either refreshed or aged out. This configuration is not supported. 160.
