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 enables opaque LSAs across the entire system:
enable ospf capability opaque-lsa
