Create an ECMP zone

Create an ECMP zone to enable load balancing across multiple equal-cost paths in a virtual router configuration.

ECMP zones are created per virtual router. Only interfaces that belong to the virtual router where the ECMP is being created can be associated with the ECMP.

Procedure


Step 1

Navigate to the Devices > Device Management, and edit the Firewall Threat Defense device.

Step 2

Click Routing.

Step 3

From the virtual router drop-down, select the virtual router in which you want to create the ECMP zone.

You can create ECMP zones in global virtual router and user-defined virtual routers. For information on creating virtual routers, see Create a Virtual Router.

Step 4

Click ECMP.

Step 5

Click Add.

Step 6

In the Add ECMP box, enter a name for the ECMP zone.

Note

The ECMP name must be unique for the routed device.

Step 7

Under the Available Interfaces box, select the interface and click Add.

  • Only interfaces belonging to the virtual router where you are creating the ECMP can be associated with it. Interfaces must have a logical name to be displayed; edit the interface and save to set a logical name.

  • From Version 10.0, ECMP is supported on dynamic VTIs (DVTIs) of hub devices in SD-WAN VPN topologies. When enabled on a DVTI, it is automatically added to a system-generated ECMP zone, so DVTIs do not appear under Available Interfaces.

Step 8

Click OK.

The ECMP page displays your newly created ECMP zone.

Step 9

Click Save and Deploy the configuration.


You can associate the ECMP zone interfaces with equal cost static route by defining them with the same destination and metric value but with a different gateway.
