Thanks, Marc for the response. However, the route was created because of
the prefix that was received in the RA. Hence it should be marked as "ra"
too. I feel that makes more sense. We will be able to correctly identify
all the routes that were added due to a received RA.

I can only guess, but my guess is that it doesn't marked that way
because it strictly speaking didnt come from an RA but was generated
because an IP address was configured on the Interface. That is most
probably the same mechanism that is used when an IP address is manually configured on the interface.
When I flush the ra learned routes using the following command, only the default route gets removed. Why doesn't the prefix which is *bolded*
above
get deleted too?
Because the route was not learned via RA. I find that correct behavior.
