I know the ARP table is cached data.
On Juniper, we can use show arp
to query the arp table:
admin@juniper> show arp | match "16.23.43.75"
ac:1f:6b:90:d1:ca 16.23.43.75 16.23.43.75 ae16.83
none
But the arp is not a real-time table, you know.
If we shutdown the 16.23.43.75
server, we can still query out the 16.23.43.75
record.
Is there a way to refresh the arp table in the case do not affect other routing?
