    Is it possible to configure subscribers in a shared vlan as in the example below?

     

    OLT <-vlan 10 + dhcp option82 circuit id-> JUNIPER -> subscribers sessions share the vlan 10. Authentiction information are sent via radius using dhcp option82 as username-password and radius returns informations like Framed-IP-Address, shapping rate.

    Hi,

     

    Yes this is possible.

     

    test# set system services dhcp-local-server group test authentication username-include option-82
    test# set forwarding-options dhcp-relay group test authentication username-include option-82

     

    Regards,

    Rahul

    Yes, its possible.. Here is sample DHCP configuration:

     

    labroot@jtac-MX960-r2004-re0# show system services dhcp-local-server
    authentication {
    password globe;
    username-include {
    domain-name test.com;
    mac-address;
    option-82 circuit-id;
    }
    }
    dynamic-profile IPoE;
    group globe {
    interface xe-5/0/0.0;
    interface demux0.0;
    }

     

    You can return the IP from framed-ip-addr VSA from radius or can configure local ip address local.

    For, Shapping rate, you either configure dynamic-profile on MX that includes all the specfic service filter, policy and return Unisphere-Activate-Service-tag-1 VSA from Radius.
