ECMP routing methods

ECMP is a routing method that

  • enables traffic distribution across multiple equal-cost paths,

  • supports up to 8 equal cost static or dynamic routes across up to 8 interfaces within each zone, and

  • uses traffic zones per virtual router to contain a group of interfaces.

Multiple default routes configuration

This example shows multiple default routes configured across three interfaces in the zone:

route for 0.0.0.0 0.0.0.0 through outside1 to 10.1.1.2

route for 0.0.0.0 0.0.0.0 through outside2 to 10.2.1.2

route for 0.0.0.0 0.0.0.0 through outside3 to 10.3.1.2
