Data Plan
The data provided in this section is used as an example, which may vary depending on the network scale and topology.
Parameter |
Value |
Remarks |
|---|---|---|
mpls te |
- |
Enable MPLS TE. |
mpls rsvp-te |
- |
Enable MPLS RSVP-TE. |
mpls rsvp-te hello |
- |
Enable the RSVP Hello extension mechanism. |
mpls rsvp-te hello full-gr |
- |
Enable the RSVP GR and RSVP GR Helper capabilities of the GR node. |
mpls te cspf |
- |
Enable the MPLS TE CSPF algorithm. |
Parameter |
Value |
Remarks |
|---|---|---|
interface Tunnel |
Number of a tunnel interface |
It is recommended that tunnel IDs be associated with device names and descriptions be added for tunnel interfaces. |
ip address unnumbered |
interface LoopBack1 |
Configure a tunnel interface to borrow an IP address from loopback interface 1. |
tunnel-protocol |
mpls te |
Enable the TE tunnel function. |
destination |
IP address of remote loopback interface 1 |
Specify the destination IP address. |
mpls te tunnel-id |
Tunnel ID |
Set a tunnel ID. |
mpls te affinity property |
Configure the affinity attribute for the primary and backup CR-LSPs based on link management group attributes. |
- |
mpls te backup |
hot-standby |
Configure the hot standby mode of the tunnel. |
bfd bind mpls-te interface Tunnel te-lsp |
discriminator local discriminator remote detect-multiplier min-tx-interval min-rx-interval process-pst |
Configure static BFD to detect the backup CR-LSP of a TE tunnel. Set the local discriminator of the local system to be the same as the remote discriminator of the remote system, and adjust the local detection multiplier of BFD. Set the minimum interval at which BFD packets are sent and received to 3.3 ms. Allow BFD sessions to change the PST to speed up switchovers. |
bfd bind mpls-te interface Tunnel |
discriminator local discriminator remote detect-multiplier min-tx-interval min-rx-interval process-pst |
Configure static BFD to detect the primary CR-LSP of a TE tunnel. Set the local discriminator of the local system to be the same as the remote discriminator of the remote system, and adjust the local detection multiplier of BFD. Set the minimum interval at which BFD packets are sent and received to 3.3 ms. Allow BFD sessions to change the PST to speed up switchovers. |
tunnel-policy |
Tunnel policy name: TSel tunnel select-seq cr-lsp lsp load-balance-number 1 Tunnel policy on the core device: TE tunnel select-seq cr-lsp load-balance-number 1 |
Configure tunnel policies for preferentially selecting CR-LSPs. |
