  • Entries under IPv4 are reaching HW (Hardware) limitation.
Resolution
  1. Type "show iproute reserved-entries statistics" to verify to see if the entries under IPv4 are reaching HW (Hardware) limitation.
  2. Type: “enable iproute compression”
Additional notes
  • Running the command “enable iproute compression” should be used if there are more routes in this chassis that are filling up the hardware table and then it needs to be reduced.
