z Application environment
Use BFD to detect the connectivity of static LSP. BFD for static LSP can avoid the case when the
static LSP configured becomes "Down", the private-network route will not select this static LSP
as the forwarding path.
z Prerequisites
Before configuring BFD for static LSP, the following configuration must be done:
¾ Enable MPLS
¾ Configure static LSP
z Data preparation
Before configuring BFD for static LSP, the following data must be prepared:
¾ My Discriminator and Your Discriminator of BFD session
¾ Backward direction link detection mode
¾ BFD session parameters: interval for transmitting BFD control packets, interval for receiving
BFD control packets and BFD control packet detection time multiplier.
3.2.3.2 Configure BFD on Ingress 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:
Command Function
DES-7200# configure teminal
Enter global configuration mode.
DES-7200(config)# interface type
ID
Enter interface configuration mode.
