    Interface-level "dhcp relay destination" command issues

    telecom116 New Member

      I have determined the interface-level "dhcp relay destination dhcp-svr " command does not forward packets from a VLAN subinterface.  This is on a Netvanta 3450 router running R10.3.0.

       

      The commands I used that are not forwarding DHCP requests:

       

      interface eth 0/2

        encapsulation 802.1q

        no shutdown

      !

      interface eth 0/2.2

        vlan-id 1235

        ip address  172.30.21.1  255.255.255.0

        ip dhcp relay destination 172.16.21.252

        no shutdown

      !

       

      Working commands I found from the Configuring UDP Relay document:

       

      ip forward-protocol udp bootps

       

      interface eth 0/2

        encapsulation 802.1q

        no shutdown

      !

      interface eth 0/2.2

        vlan-id 1235

        ip address  172.30.21.1  255.255.255.0

        ip helper-address  172.16.21.252

        no shutdown

       

      Is this a software bug?
