hi,

'grpc error no such entry', but the overall result will be that the tcam
programmed will equal what freerouter
and i have some additional considerations here to note:
so cisco have this:

they never ever mention any automated repair actions and once when i needed
this, i realized that is really just checks....
and the fun part is that p4emu/freerouter combination already have this
functionality through the reported counters:
you can enable "debug serv p4l err" which logs all the non-existent reports
from the dataplane.
that is, if the dataplane reports a counter for 11.1.1.1/32 and freerouter
cannot find (and update the hwcntr) within
its own tables then it logs the line that this thing is excessive report...
and a not yet implemented, but could be
feature if freerouter keeps track that when it got last time a report for a
route and if it did not got a report in
a while then it also should emit a log entry....

regards,
cs
