NETGEAR 8800 Chassis Switch CLI Manual Description Disables opaque LSAs across the entire system. Syntax Description This command has no arguments or variables. Default Enabled. Usage Guidelines Opaque LSAs are a generic OSPF mechanism used to carry auxiliary information in the OSPF database. Opaque LSAs are most commonly used to support OSPF traffic engineering. Normally, support for opaque LSAs is auto-negotiated between OSPF neighbors. In the event that you experience interoperability problems, you can disable opaque LSAs. If your network uses opaque LSAs, all routers on your OSPF network should support opaque LSAs. Routers that do not support opaque LSAs do not store or flood them. At minimum a well-interconnected subsection of your OSPF network needs to support opaque LSAs to maintain reliability of their transmission. On an OSPF broadcast network, the designated router (DR) must support opaque LSAs or none of the other routers on that broadcast network will reliably receive them. You can use the OSPF priority feature to give preference to an opaque-capable router, so that it becomes the elected DR. For transmission to continue reliably across the network, the backup designated router (BDR) must also support opaque LSAs. Example The following command disables opaque LSAs across the entire system: disable ospf capability opaque-lsa disable ospf export disable ospf export [bgp | direct | e-bgp | i-bgp | rip | static] Description Disables redistribution of routes to OSPF. Syntax Description bgp Specifies BGP routes. Chapter 23. OSPF Commands | 1021
