Tunnel policy commands

Only advanced mode and expert mode support tunnel policies. For more information about system operating modes, see device management in Fundamentals Configuration Guide.

The device does not support MPLS forwarding for tunneled packets.

display mpls tunnel

Use display mpls tunnel to display tunnel information.

Syntax

display mpls tunnel { all | statistics | [ vpn-instance vpn-instance-name ] destination ipv4-address }

Views

Any view

Predefined user roles

network-admin

network-operator

Parameters

all: Displays all tunnels.

statistics: Displays tunnel statistics.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command displays tunnel information for the public network.

destination: Displays the tunnel destined for the specified address.

ipv4-address: Specifies the tunnel destination IPv4 address.

Examples

# Display information about all tunnels.

<Sysname> display mpls tunnel all

Destination      Type     Tunnel/NHLFE      VPN Instance

2.2.2.2          LSP      NHLFE1024         -

Field	Description
Destination	Tunnel destination address.
Type	Tunnel type.
Tunnel/NHLFE	Tunnel or NHLFE entry. NHLFEnumber represents the ingress LSP that matches the NHLFE entry with NID of number.
VPN Instance	VPN instance name. If the tunnel belongs to the public network, this field displays a hyphen (-).

Field	Description
LSP	Number of LSP tunnels.
GRE	This field is not supported in the current software version. Number of GRE tunnels.
CRLSP	This field is not supported in the current software version. Number of CRLSP tunnels.
SRLSP	This field is not supported in the current software version. Number of SRLSP tunnels.

display tunnel-policy

Use display tunnel-policy to display tunnel policy information.

Syntax

display tunnel-policy [ tunnel-policy-name ]

Parameters

tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 19 characters. If you do not specify a tunnel policy, this command displays information about all tunnel policies.

Examples

# Display information about all tunnel policies.

<Sysname> display tunnel-policy

Tunnel policy name   : policy1

Preferred paths      :

  Interface  : not configured

  Tunnel type: not configured

Select-Seq           : LSP

Load balance number  : 8

Strict               : no

# Display information about tunnel policy policy1.

<Sysname> display tunnel-policy policy1

Tunnel policy name  : policy1

Preferred paths     :

  Interface  : not configured

  Tunnel type: not configured

Select-Seq          : LSP

Load balance number : 1

Strict              : no

Table 3 Command output

Field	Description
Select-Seq	Tunnel selection order. The tunnel types are displayed in descending order of priority in tunnel selection.
Load balance number	Number of tunnels for load balancing.
Strict	Whether the strict method is used to select tunnels for load balancing: ·     no—The tunnel policy can use a hybrid of the specified types of tunnels for load balancing. ·     yes—The tunnel policy uses only one type of tunnels for load balancing.
Preferred paths	Information about preferred tunnels.
Type	Tunnel type.
Tunnel	Tunnel name.
Preference	Preference value of the preferred tunnel.

‌

select-seq load-balance-number

Use select-seq load-balance-number to configure the tunnel selection order and set the number of tunnels for load balancing.

Use undo select-seq to restore the default.

Syntax

select-seq [ strict ] lsp load-balance-number number

undo select-seq

Default

The device selects one tunnel from all available tunnels.

Parameters

strict: Uses the same type of tunnels for load balancing. If you do not specify this keyword, the device can use a hybrid of the specified types of tunnels for load balancing.

lsp: Uses LSP tunnels.

load-balance-number number: Specifies the number of tunnels for load balancing, in the range of 1 to 16.

Usage guidelines

A tunnel type closer to the select-seq keyword has a higher priority, and only the tunnel types specified in this command can be used.

If strict mode is disabled, the device can use different types of tunnels for load balancing. If strict mode is enabled, the device can only use tunnels of the same type for load balancing.

For example, specify three tunnels for load balancing and gives LSPs higher priority over CRLSPs.

·     If you execute the select-seq lsp cr-lsp load-balance-number 3 command, the VPN can use CRLSPs when the number of LSPs is fewer than three or no LSPs are available.

·     If you execute the select-seq strict lsp cr-lsp load-balance-number 3 command, the VPN can use CRLSPs only if no LSPs are available. It cannot use a mixture of LSPs and CRLSPs for load balancing.

This method selects tunnels randomly, making it hard to plan VPN traffic paths. As a best practice, use this method only if necessary.

If you use both the select-seq load-balance-number and preferred-path commands for a tunnel policy, the tunnel policy selects tunnels in the following steps:

1.     If the destination address of the preferred tunnel identifies a peer PE, the tunnel policy uses the preferred tunnel to forward traffic destined for the peer PE.

2.     If not, the tunnel policy selects tunnels as configured by the select-seq load-balance-number command.

Examples

# Configure tunnel policy policy1 to use only LSP tunnels, and set the load balancing number to 2.

<Sysname> system-view

[Sysname] tunnel-policy policy1

[Sysname-tunnel-policy-policy1] select-seq lsp load-balance-number 2
