Important Points to Remember
• If the target VRF conatins the same prefix as either the sourced or Leaked route from some other VRF, then route Leaking
for that particular prefix fails and the following error-log is thrown.
SYSLOG (“Duplicate prefix found %s in the target VRF %d”, address, import_vrf_id) with
The type/level is EVT_LOGWARNING.
• The source routes always take precedence over leaked routes. The leaked routes are deleted as soon as routes are locally
learnt by the VRF using other means.
• For recovery, you must take appropriate action either by deleting the unwanted prefixes or issuing clear command or both.
• In the target VRF, you cannot leak routes that are imported through the route leaking feature.
• The leaked route points to the next-hop of the source routes. You cannot do any modifications to the next-hop of the
leaked route in the destination VRF.
• IPv6 link local routes will never be leaked from one VRF to another.
