Configuring an HoVPN

Configuring an HoVPN

Context

In addition to basic BGP/MPLS IP VPN configuration, you need to specify UPE devices on the SPE device and advertise default routes of VPN instances to the UPE devices.

When VPN services need to be transmitted over TE tunnels or when multiple tunnels need to perform load balancing to fully use network resources, you also need to configure tunnel policies. For details, see Configuring Tunnel Policies.

Perform the following steps on the SPE device. (The configuration is not required on UPE and NPE devices.)

Procedure

  1. Specify a UPE device.
    1. Run system-view

      The system view is displayed.

    2. Run bgp { as-number-plain | as-number-dot }

      The BGP view is displayed.

    3. Run peer { ipv4-address | group-name } as-number as-number

      A UPE device is specified as the BGP peer of the SPE.

    4. Run ipv4-family vpnv4 [ unicast ]

      The BGP-VPNv4 family is displayed.

    5. Run peer { ipv4-address | group-name } enable

      The capability of exchanging BGP VPNv4 routing information with the peer is enabled.

    6. Run peer { ipv4-address | group-name } upe

      The peer is specified as the UPE of the SPE.

  2. Advertise default routes of a VPN instance.
    1. Run system-view

      The system view is displayed.

    2. Run bgp { as-number-plain | as-number-dot }

      The BGP view is displayed.

    3. Run ipv4-family vpnv4

      The BGP-VPNv4 family view is displayed.

    4. Run peer { ipv4-address | group-name } default-originate vpn-instance vpn-instance-name

      The default routes of a specified VPN instance are advertised to the UPE device.

      After running the command, the SPE advertises a default route to the UPE with its local address as the next hop, regardless of whether there is a default route in the local routing table.
