Stupid situation if device X tries to communicate with Bob, but Bob send no answer to request. Bob has a problem, his ARP table is broken and he cant reach X.
Solve this problem by clearing the ARP information table:
Flush all arp enties on interface eth1:
1 | ip neigh flush dev eth1 |
Flush arp entry for host 10.1.100.40:
1 | ip neigh flush 10.1.100.40 |
Flush ARP entry for for network 192.168.222.0/21:
1 | ip neigh flush 192.168.222.0/21 |
Flush all ARP entries:
1 | ip neigh flush all |
Show ARP Table:
1 | arp -a |
