VPN 3030 and OSPF configuration

    Current Configuration:
    -----------------------

    VPN_Concentrator_3030_Public_Interface -----> 6509 (vlan int 999)
    VPN_Concentrator_3030_Private_Interface ------> 6509 (vlan int 888)

    We are not following Cisco's symantic of public, private and external
    interfaces suggested in documentation.

    Private interface is only used for Managemnt.

    5 groups are configured on Concentrator. Aggregate block is
    172.31.0.0/24

    Static route is installed on 6509.
    # ip route 172.31.0.0 255.255.255.0 PUBLIC_INTERFACE_OF_CONCENTRATOR

    Everything works.

    Desired Configuration:
    -----------------------
    We would like to have OSPF between 6509 and Concentrator, instead of
    using static routes.
    Enabled OSPF on PUBLIC_INTERFACE_OF_CONCENTRATOR.
    Reverse Route Ijection: is setup properly and have
    172.31.0.0/255.255.255.0 in hold down routes.

    Problem:
    --------
    OSPF is up between 6509 and PUBLIC_INTERFACE_OF_CONCENTRATOR.
    Concentrator gets all the Routes from 6509.
    But, Concentrator is NOT feeding 172.31.0.0/24 routes in OSPF. Thus
    6509 is NOT seeing 172.31.0.0/24 routes from Concentrator.

    Any pointers would be appreciated.

    Thanks.

  3. I do have all params. configured. 'sh ip ospf nei' on 6509 give me
    Concentrator as ospf neighbour.
    Also VPN_Concentrator gets all the routes from 6509.

    But, Concentrator is NOT able to feed ip block (used by groups defined
    on concentrator) into OSPF area.

    Thanks.
