Introducing OSPF with ABR
SteelHead SD provides single and multiple area OSPF with ABR and route redistribution between OSPF
zone interfaces and ABRs on the LAN side of the network. You can configure OSPF regardless of whether
it is a zone or an uplink.
SteelHead SD supports OSPF for a branch site with one or two MPLS providers, where each provider is
connected to a customer edge (CE) router. A SteelConnect branch gateway is deployed in front of the
CE routers. The provider edge (PE) routers on the MPLS WAN side are using BGP and the CE routers on
the LAN side are using OSPF.

Important: Before you begin configuring OSPF for SteelHead SD, we recommend you consult the SteelConnect
Manager User Guide .
Creating an OSPF network
You create OSPF networks at the site level. Before configuring OSPF, make sure the appliance is
registered in SCM and that OSPF is enabled on any routing device that will peer with the appliance. You
create an OSPF network based on a site location that includes one area and then you attach one or more
interfaces to the OSPF area.
To create an OSPF network
1. Deploy the SteelHead SD and assign a zone and uplink to a port.
