[M/MX] Directed broadcast supported on MPCs only in enhanced-ip mode



Article ID: KB24389 KB Last Updated: 04 Aug 2020Version: 2.0

This article provides information about the support extended by MPCs for directed broadcast.



A customer was trying to configure and set up Wake-on-Lan on their MX960 platform. They were able to successfully do so on the EX platform; but are having difficulties on the MX platform. They have enabled the option for broadcasting; but this did not have any effect.

They are using an IRB, rather than a physical/logical interface. To enable this, the customer has to enable targeted-broadcast on the interface <name> unit <number> family inet, in which the unit is the one that contains the IP address of the router for machines on the network. However, the wake-on-lan feature was not functioning in ICHIP based platforms. This feature uses Directed Broadcast on IRB.



Directed broadcast on IRB is supported only on TRIO based platforms in enhanced-ip mode. Juniper does not plan on supporting this feature on ICHIP-based platforms.
