Specifying ASBRs

ASBRs advertise non-OSPF routes into OSPF domains so that they can be passed along throughout the OSPF routing domain. A router can function as an ASBR if one or more of its interfaces is connected to a non-OSPF network (for example, RIP, BGP, or EGP).

To conserve resources, you may want to limit the number of ASBRs in your network or to specifically control which routers perform as ASBRs to control traffic flow.

To specify whether or not a router should be an ASBR:

  1. From the Device Manager menu bar, choose IP Routing > OSPF > General.
    2. The OSPF dialog box opens with the General tab displayed.
  2. From the ASBdrRtrStatus field, select true to designate the router as an ASBR or false to remove ASBR status from the router.
  3. Click Apply.
