Configuring BFD for LSP

Procedure

• Configure SPEs.

  The following uses the configuration of Core_SPE1 on the core ring as an example. The configurations of Core_SPE2 and Core_SPE3 are similar to the configuration of Core_SPE1, and are not mentioned here.

  bfd SPE1toSPE2 bind ldp-lsp peer-ip 172.16.0.3 nexthop 172.17.4.9 interface Eth-Trunk4    //Enable static BFD to detect the LDP LSP between SPE1 and SPE2.
   discriminator local 317    //Set the local discriminator. The local discriminator of the local system must be the same as the remote discriminator of the remote system.
   discriminator remote 137    //Set the remote discriminator.
   detect-multiplier 8    //Set the local detection multiplier of BFD.
   min-tx-interval 3    //Set the minimum interval at which the local device sends BFD packets to 3.3 ms.
   min-rx-interval 3    //Set the minimum interval at which the local device receives BFD packets to 3.3 ms.
   process-pst    //Allow BFD sessions to change the PST to speed up switchovers.
   commit    //Commit the BFD session configuration.

  bfd SPE1toSPE3 bind ldp-lsp peer-ip 172.16.0.4 nexthop 172.17.4.3 interface Eth-Trunk5    //Enable static BFD to detect the LDP LSP between SPE1 and SPE3.
