arp_update should resolve the missing arp/ndp static route entries. Added code to check for missing entries and try ping to resolve the missing entry. Why I did it Fixes sonic-net#14179 chassis-packet: missing arp entries for static routes causing high orchagent cpu usage It is observed that some sonic-mgmt test case calls sonic-clear arp, which clears the static arp entries as well. Orchagent or arp_update process does not try to resolve the missing arp entries after clear. How I did it arp_update should resolve the missing arp/ndp static route entries. Added code to check for missing entries and try ping if any found to resolve it. How to verify it After boot or config reload, check ipv4 and ipv4 neigh entries to make sure all static route entries are present manual validation: Use sonic-clear arp and sonic-clear ndp to clear all neighbor entries run arp_update Check for neigh entries. All entries should be present. Signed-off-by: anamehra <anamehra@cisco.com>
