irb ifl disable does not remove EVPN arp entries.

Deactivate/delete irb interface removes arp-table correctly.

The Junos routing architecture treats addresses assigned to disabled interfaces as “inactive” but does not immediately remove them from the routing table. Instead, the default behavior for such routes is to reject traffic. This occurs because the IRB IFL is still defined, and the IP address remains configured, even though the IRB interface is in a disabled state.

To ensure that the router does not “own” the IP address assigned to the IRB IFL, the IRB IFL must either be fully deactivated or deleted.
