How does the tunnel management module select tunnels in multi-path load balancing on S series switches

12

Q: How does the tunnel management module select tunnels in multi-path load balancing?
If the number of tunnels for load balancing is set to 6 and eight LSP tunnels are available, how are tunnels selected during tunnel iteration?
If a selected tunnel is in Down state, what will the tunnel management module select tunnels?
If the selected tunnel becomes Up, what will the tunnel management module select tunnels?
Q: TNLM randomly selects six tunnels and returns the tunnels to RM.
If the state of a selected tunnel changes, for example, the Down state, TNLM selects one tunnel from the two alternate tunnels.
If the selected tunnel becomes Up and the number of tunnels for load balancing is smaller than 6, TNLM selects another six tunnels for RM. Otherwise, the Up and Down states of a tunnel have no impact on load balancing.

If the selected tunnel state changes, such as the first down, a tunnel is randomly selected from the alternate tunnel.

How to select a tunnel among multiple tunnels working in load balancing mode
If the number of tunnels is set to 6 for load balancing, how to select six LSP tunnels from eight ones during tunnel iteration? If the selected tunnels enter the Down state, how to re-select tunnels? If the selected tunnels go Up from the Down state, how to re-select tunnels? The TNLM randomly selects six tunnels and then returns them to the RM. If the status of the selected tunnels changes (for example, the first tunnel enters the Down state), the TNLM randomly selects another tunnel from two candidate ones. If the tunnels go Up from the Down state and there are fewer than six tunnels for load balancing, the TNLM is triggered to re-select six tunnels and then returns them to the RM. Otherwise, the status of tunnels does not affect load balancing.

How to check the path of an MPLS TE tunnel on S series switches
For S series switches (except the S1700), run the display mpls te tunnel path command to check the path of an MPLS TE tunnel after the mpls te record-route label command is configured in the tunnel view. display mpls te tunnel path Tunnel Interface Name : Tunnel6/0/0 Lsp ID : 23.23.23.23 :2 Hop Information Hop 0 3.23.24.1 Hop 1 3.23.24.2 Label 1024 Hop 2 2.2.2.2
