  • 1.  SRX sends ARP requests for some non-using IP address

    Posted 09-16-2024 03:25

    Hello folks,

    I see on my srxk5 rel21.2r3 that FXP0.0 is sending out ARP request for some not-used (not added in the configuration) IP addresses. 

    Is that expected?

    Is there any way to deeply check this?

    Many thanks for your help

    If proxy arp is setup for that ip address this might occur, but from your description that probably is not the case.

    The other possibility is that the ip address is in the same vlan as the fxp0.0 interface and the interface is responding with flooding for normal layer 2 requests for the host ip.
