Configuring Tunnel Load Balancing

Run system-view

The system view is displayed.
Run tunnel-policy policy-name

A tunnel policy is created.
(Optional) Run description text
A description is configured for the tunnel policy.
Run tunnel select-seq { gre | lsp | cr-lsp } ^* load-balance-number load-balance-number
The sequence in which each type of tunnel is selected and the number of tunnels participating in load balancing are configured.
Apply the tunnel policy.
- Apply the tunnel policy to BGP/MPLS IP VPN:
  1. Run system-view
    The system view is displayed.
  2. Run ip vpn-instance vpn-instance-name
    The VPN instance view is displayed.
  3. Run ipv4-family
    The VPN instance IPv4 address family view is displayed.
  4. Run tnl-policy policy-name
    The tunnel policy is applied to the VPN instance IPv4 address family.
- Apply the tunnel policy to a BGP/MPLS IPv6 VPN.
  1. Run system-view
    The system view is displayed.
  2. Run ip vpn-instance vpn-instance-name
    The VPN instance view is displayed.
  3. Run ipv6-family
    The VPN instance IPv6 address family view is displayed.
  4. Run tnl-policy policy-name
    The tunnel policy is applied to the VPN instance IPv6 address family.
- Apply the tunnel policy to an SVC VLL.
  1. Run system-view
    The system view is displayed.
  2. Run interface interface-type interface-number
    The AC interface view is displayed.
  3. To apply the tunnel policy to a VC of an SVC VLL, run the following commands based on interface types:
    - Ethernet interface: mpls static-l2vc { { destination ip-address | pw-template pw-template-name vc-id } ^* | destination ip-address [ vc-id ] } transmit-vpn-label transmit-label-value receive-vpn-label receive-label-value [ tunnel-policy tnl-policy-name [ endpoint endpoint-address color color-value ] | access-port | [ control-word | no-control-word ] | [ raw | tagged | ip-interworking ] ] ^*
- Apply the tunnel policy to an LDP VLL.
  1. Run system-view
    The system view is displayed.
  2. Run interface interface-type interface-number
    The AC interface view is displayed.
  3. To apply the tunnel policy to a VC of an LDP VLL, run the following commands based on interface types:
    - Ethernet interface: mpls l2vc { ip-address | pw-template template-name } ^* vc-id [ tunnel-policy policy-name [ endpoint endpoint-address color color-value ] | [ control-word | no-control-word ] | [ raw | tagged | ip-layer2 | ip-interworking ] | access-port | ignore-standby-state ] ^*
- Apply the tunnel policy to a LDP VPLS.
  1. Run system-view
    The system view is displayed.
  2. Run vsi vsi-name [ auto | static ]
    A VSI is created.
  3. Run pwsignal ldp
    The PW signaling protocol is set to LDP and the VSI-LDP view is displayed.
  4. Run vsi-id vsi-id
    A VSI ID is set.
  5. Run peer peer-address [ negotiation-vc-id vc-id ] tnl-policy policy-name
    The tunnel policy is applied to a VSI peer.
- Apply the tunnel policy to a PWE3.
  1. Run system-view
    The system view is displayed.
  2. Run interface interface-type interface-number
    The AC interface view is displayed.
  3. Choose one of the following options to apply the tunnel policy to a PW.
    - For a dynamic PW, run the mpls l2vc { pw-template pw-template-name | ip-address } ^* vc-id tunnel-policy policy-name command.
    - For a static PW, run the mpls static-l2vc { { destination ip-address | pw-template pw-template-name vc-id } ^* | destination ip-address [ vc-id ] } transmit-vpn-label transmit-label-value receive-vpn-label receive-label-value tunnel-policy tnl-policy-name command.
Run commit
The configuration is committed.

Follow-up Procedure

Run the save command to save the current configuration to the configuration file when a set of configuration is finished and the expected functions have been achieved.
