Does vMX support DHCP discover from relay agent ?

  • 1.  Does vMX support DHCP discover from relay agent ?

    I configured vMX as a DHCP server. It works fine with the local DHCP clients, but not work for the remote clients via relay agent.

    I have the following configuration.

    set access address-assignment pool vlan56 family inet network 10.100.56.0/24
    set access address-assignment pool vlan56 family inet range r1 low 10.100.56.20
    set access address-assignment pool vlan56 family inet range r1 high 10.100.56.30
    set access address-assignment pool vlan100 family inet network 10.100.100.0/24
    set access address-assignment pool vlan100 family inet range r1 low 10.100.100.20
    set access address-assignment pool vlan100 family inet range r1 high 10.100.100.30

    The group in Red for the remote clients.

    set system services dhcp-local-server group jncie interface irb.56

    the log shows the following when receiving the discover packet from the relay agent.

    Dec 20 01:31:07.649976 [MSTR][DEBUG][default:default][SVR][INET][irb.56] jdhcpd_find_client_from_client_pdu: BOOTPREQUEST could not find client table ent

    I tried to configure pool under system services dhcp stanza, but vmx does not support.

    root@vMX5# show system services

    dhcp-local-server {

        group jncie {

            interface irb.56;

        }

    }

    dhcp {

        pool 10.100.100.0/24 {

            address-range low 10.100.100.25 high 10.100.100.30;

            router {

                10.100.100.254;

            }

        }

    }

    any ideas ?

    thanks in advance !!
