How to check the path of an MPLS TE tunnel on S series switches

17

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

How to configure MPLS TE on S series switches
Multiprotocol Label Switching Traffic engineering (MPLS TE) can prevent congestion caused by improper resource allocation by allocating some traffic to idle links, allowing network traffic to be allocated properly. The MPLS TE configurations on different switch models are the same. For details, see "CLI-based Configuration > Configuration Guide - MPLS > MPLS TE Configuration" in S7700&S9700 V200R010C00 Product Documentation.

How are RSVP-TE path messages forwarded on the MPLS network
Generally, RSVP-TE Path messages are forwarded on the MPLS network using IP routes. In the scenario where the primary CR-LSP is faulty (that is, the primary CR-LSP is in FRR in-use state) and the TE FRR bypass tunnel is used, RSVP-TE Path messages are forwarded over the TE tunnel.

How to import traffic to a TE tunnel on S series switches
For S series switches (except the S1700), use either of the following methods to import traffic to the TE tunnel: - Configure static routes. For example, after you run the ip route-static 10.0.0.0 24 tunnel1/0/0 command, traffic destined for 10.0.0.0/8 is forwarded through Tunnel1/0/0. - Configure auto routes in IGP shortcut mode. After the auto routes are configured in IGP shortcut mode, TE tunnels act as logical links to participate in IGP route calculation and tunnel interfaces are used as the outbound interfaces of the ingress routers, and do not affect the IGP route calculation by other routers.

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