    Dear Guys,

     

    I have a problem with MX40 dhcp relay over VRF.  DHCP server located at the remote site.

     

    DHCP relay status showing in SELECTING state and PC didnt get ip addr.

     

    elchin@CAMP-MX#run show dhcp relay binding routing-instance BBB detail

     

    Client IP Address: 0.0.0.0
    Hardware Address: 1c:75:08:35:6c:06
    State: SELECTING(RELAY_STATE_SELECTING)
    Lease Expires: unknown
    Lease Expires in: 0 seconds
    Lease Start: unknown
    Last Packet Received: 2016-02-24 15:47:50 AZT
    Incoming Client Interface: ge-1/1/1.613(irb.613)
    Server Ip Address: 0.0.0.0
    Server Interface: none
    Bootp Relay Address: 10.11.50.1
    Session Id: 19 

     

    Here is the configuration:

     

    Interface conf:

     

    elchin@CAMP-MX#show interfaces ge-1/1/1
    description BBB;
    vlan-tagging;
    encapsulation flexible-ethernet-services;
    unit 111 {
    encapsulation vlan-vpls;
    vlan-id 111;
    }
    unit 613 {
    description CAMP1;
    encapsulation vlan-bridge;
    vlan-id 613;
    family bridge;
    }

    [edit]

     

    elchin@CAMP-MX# show interfaces irb
    unit 613 {
    family inet {
    address 10.10.50.1/24;
    address 10.11.50.1/24;
    address 10.16.50.1/24;
    }

    Bridge domain conf: 

     

    elchin@CAMP-MX# show bridge-domains
    VLAN613 {
    domain-type bridge;
    vlan-id 613;
    interface ge-1/1/1.613;
    routing-interface irb.613;

     

    VRF conf:

     

    elchin@CAMP-MX# show routing-instances BBB
    instance-type vrf;
    system {
    services {
    dhcp-local-server {
    group default-group {
    interface lsi.0 {
    upto lsi.16385;
    }
    }
    }
    }
    }
    interface irb.613;
    route-distinguisher 65100:22;
    vrf-target target:65100:22;
    vrf-table-label;
    routing-options {
    router-id 10.10.30.8;
    }
    forwarding-options {
    dhcp-relay {
    server-group {
    SRV {
    10.10.7.2;
    }
    }
    active-server-group SRV;
    group all {
    active-server-group SRV;
    interface irb.613;
    }
    }
    }

     

     Thanks in advance.
