3.3.14.2 Configuring BFD for Detecting Dynamic LSP
Command Function
DES-7200>enable
Enter privileged mode
DES-7200# configure terminal
Enter global configuration mode
DES-7200#mpls router ldp
Enter LDP configuration mode
DES-7200(config-mpls-router)# bfd
bind ldp-lsp peer-ip ip-address
nexthop ip-address interface type
number local-discriminator number
remote-discriminator number
process-state
Configure BFD for detecting dynamic LSP
and handle BFD session state. You can
configure the peer IP address, the next-hop
address and the egress interface of LSP.
If no local discriminator is configured, the
system will automatically select the local
discriminator. If no remote discriminator is
configured, the system will use
auto-configuration to learn the remote
discriminator.
3.3.14.3 Configuring BFD for Detecting Backward LSP with IP
Command Function
DES-7200>enable
Enter privileged mode
DES-7200# configure terminal
Enter global configuration mode
DES-7200#mpls router ldp
Enter LDP configuration mode
DES-7200(config-mpls-router)# bfd
bind backward-lsp-with-ip peer-ip
ip-address interface type number
source-ip ip-address
local-discriminator number
remote-discriminator number
Configure BFD for detecting backward LSP
with IP. You can configure the source IP
address, peer IP address and the egress
interface of LSP.
The local discriminator and remote
discriminator must be configured manually.
To learn more details about BFD for MPLS-LSP and the command reference,
please refer to the documents named "MPLD-CERF" and "MPLS-SCG".
