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 { cr-lsp | lsp } * load-balance-number number
undo select-seq
Default
The device selects only one tunnel in LSP-CRLSP order.
Views
Tunnel policy view
Predefined user roles

Parameters
cr-lsp: Uses CRLSP or SRLSP tunnels.
lsp: Uses LSP tunnels.
load-balance-number number: Specifies the number of tunnels for load balancing. The value range is 1 to 32.
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. For example, the select-seq lsp cr-lsp load-balance-number 3 command gives LSP higher priority over CRLSP. If no LSP is available or the number of LSPs is less than 3, VPN uses MPLS TE tunnels.
Tunnels selected by this method are not fixed, making it hard to plan VPN traffic. As a best practice, do not use this method.
When you configure both the select-seq load-balance-number and preferred-path commands for a tunnel policy, the tunnel policy selects tunnels in the following steps:
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.
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 MPLS TE tunnels, and set the load balancing number to 2.
