Symptom
Devices responds on ARP requests for an IP-address it does not own.
The IP-address is seen in respective alias table (unexpectedly).
Conditions
Sequence of events:
1. a NAT statement was created with "match-in-vrf stateless" keywords;
2. this expectedly creates ip alias (should an IP-address be on connected subnet)
3. the NAT stetement is removed without the "match-in-vrf stateless" keywords in "no" command.
(optionally it could be removed via netconf with the same outcome)
Now alias is stuck without parent NAT statement.
Workaround
To address stuck aliases: reload the device.
To avoid hitting the issue: use full command with all keywords to remove NAT statement (does not apply to netconf)
