In the filtered "ps" output shown above, we see three processes corresponding to the OSPF instances running
in each VRF. The OSPF task _without_ the "vrfid" and "vrfname" arguments is the one running in the default
VRF. Each protocol process running in a non-default VRF will have "vrfid" and "vrfname" arguments. Those
arguments tell us how to map VRF names to vrfids. Above, you can see that "vrfname b" is on the same line as
"vrfid 2". So to control OSPF switch logging in VRF "b", we use switch logging application name "ospf_2".
Similarly, to control OSPF switch logging in VRF "a", we use switch logging application name "ospf_1".
{{Note|It's a coincidence that VRF name "a" happens to be vrfid 1 and vrf name "b" happens to be vrfid 2. The
association between VRF names and vrfids is often less straightforward than that.}
Logging to SWLOG
All OSPF switch logging is emitted at level "debug2". If logging subapp is set to anything less than debug2, no
log messages in the corresponding category will be emitted. Available subapps:
