  • Cisco Carrier Routing System

Known Affected Releases

5.2.2.FWDG

Description (partial) 

Symptom:
a host route (i.e. /32 or /128) that was imported into a VRF will remain present in that VRF when the import is unconfigured, if there is another non-connected route in the VRF that covers the host route (and is more specific than its connected cover).

If the route remains then forwarding to that route will be broken.

Conditions:
VRF import.
