You can configure the Branch Gateway as an OSPF Autonomous System Boundary Router (ASBR) using route redistribution. The Branch Gateway can be installed in the OSPF backbone area (area 0.0.0.0) or in any OSPF area that is part of a multiple areas network. However, the Branch Gateway cannot be configured to be an OSPF area border router itself.

The Branch Gateway supports the ECMP equal-cost multipath (ECMP) feature which allows load balancing by splitting traffic between several equivalent paths.

While you can activate OSPF with default values for each interface using a single command, you can configure many of the OSPF parameters.
