Configure BFD session parameters.
DES-7200(config-if-type ID)# exit
Exit interface configuration mode.

Configure BFD for static LSP and handle BFD
session state. The peer IP address of this LSP is
10.10.10.10; the next-hop address is 1.1.1.2; the
egress interface is gigabitEthernet 0/2.
For manual configuration mode: configure my
discriminator as 1 and your discriminator as 2.
If the Ingress LSR is manually configured, then the
Egress LSR shall be manually configured as well,
which means configurations at both ends shall be
symmetrical.
To disable BFD for static LSP, execute "no bfd bind static-lsp peer-ip 10.10.10.10 nexthop
1.1.1.2 interface gigabitEthernet 0/2".
Caution
1、 BFD for static LSP can only support the static LSP established by the host
routing table.
2、 For certain applications needing BFD to detect faults (such as BFD for
LSP), the process-state parameter must be configured.
3、 If the discriminators are configured manually, then My Discriminator and
Your Discriminator configured on Ingress LSR must correspond to My
Discriminator and Your Discriminator configured on Egress LSP.
3.2.3.3 Configure BFD on Egress LSR
By default, BFD for static LSP is disabled on the device. To enable BFD for static LSP, enter
privileged user mode and execute the following steps to configure BFD for static LSP:
