[Ndn-interest] Forwarding states impact on FIB

The answer depends on the routing protocol.  I assume RED means the link corresponding to the face is physically down.  A typical dynamic routing protocol is likely to remove that face from the associated entry after the face remains RED for a period.  But a static routing protocol that doesn’t react to link failures will not.

Hi everyone,

Regarding face colors(GREEN, YELLOW and RED) and their impact on routing, I wonder if there is any relation between those two. I know colors are taken into account by forwarding plane while FIB entries are taken care of by routing plane. My question is: If a face remains RED for a period, is it going to be an update in FIB with regard to delete that face from its associated entry? Since updating FIB typically comes from RIB, then I guess for such an update routing protocol should decide.
