Common configuration tasks

This section provides a brief overview of the tasks that must be performed to configure a VPRN service and provides the CLI commands:

  1. Enabling BGP in the global routing context is needed in some configurations; for example, MVPN in PIM-SM.

    To configure BGP for the router, see the 7705 SAR Routing Protocols Guide, ‟BGP”

  2. Associate a VPRN service with a customer ID.

  3. Define a route distinguisher (RD) (mandatory).

  4. Set the auto-bind-tunnel parameter. Alternatively, define a VPRN spoke SDP. When using the vprn>spoke-sdp command, you must enter the command for each peer PE router.

  5. Define VRF route-target associations or VRF import/export policies.

  6. Define PIM parameters (optional).

  7. Define OSPF parameters (optional).

  8. Create a VPRN interface.

  9. Define SAP parameters on the VPRN interface:

    • select nodes and ports

    • optional – select QoS policies other than the default (configured in the config>qos context)

    • optional – select filter policies (configured in the config>filter context)

    • optional – select accounting policy (configured in the config>log context)

    • optional – configure DHCP features

  10. Define BGP parameters for the VPRN (config>service>vprn>bgp) (optional).

  11. Define RIP parameters (optional).

  12. Define spoke SDP parameters on the VPRN interface.

  13. Configure VRRP (optional).

  14. Enable the service.
