heartbeat-address (MX Series Virtual Chassis)

date_range 19-Nov-23

Syntax

content_copy zoom_out_map
heartbeat-address (ip-address | ipv6-address);

Hierarchy Level

content_copy zoom_out_map

Description

Configure an IPv4 address or IPv6 address used to create an IP-based packet connection, known as a heartbeat connection, between the primary router and backup router in an MX Series Virtual Chassis. To ensure consistent access to the primary Routing Engine in the Virtual Chassis primary router (VC-Pp) regardless of which Routing Engine is active, you must configure the address for the management Ethernet interface (fxp0) with the master-only statement at the [edit groups] hierarchy level.

Note:

The heartbeat-address statement and the no-split-detection statement at the [edit virtual-chassis] hierarchy level are mutually exclusive. As a result, the software prevents you from configuring both heartbeat-address and no-split-detection at the same time. If you attempt to do so, the software displays an error message and causes the commit operation to fail.

Options

ip-address

IPv4 master-only address for the fxp0 management interface.

ipv6-address

IPv6 master-only address for the fxp0 management interface.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 14.1.
