Application types of BFD
The ISCOM2600G-HI series switch supports the following BFD applications:

BFD based on IP link: establish a BFD session on the IP link and use the BFD detection
mechanism to detect faults rapidly. The ISCOM2600G-HI series switch supports single-
hop IP detection or multi-hop IP detection on the IP link.
– Single-hop IP detection: BFD rapidly detects communication faults between systems
and supports IP connectivity detection between directly-connected devices.
– Multi-hop IP detection: BFD rapidly detects communication faults between systems
and supports IP connectivity detection between indirectly-connected devices.

BFD based on LSP: establish a BFD session on the LSP link and use the BFD detection
mechanism to detect faults of the LSP link rapidly. This BFD mode provides end-to-end
protection.

BFD based on PW: a mechanism for detecting faults of the L2VPN network. The
L2VPN network rapidly detects faults of the Tunnel or PW, and guides the rapid
switching of carried services, thus protecting services.

BFD based on CR-LSP: use BFD to detect CR-LSP and thus rapidly detect LSP faults,
thus triggering the switching of service traffic among different CR-LSPs in the same TE
Tunnel.

BFD based on ISIS

BFD based on OSPF
9.5.2 Preparing for configurations
Scenario
To reduce effect of faults on services and improve network availability, the ISCOM2600G-HI
series switch needs to detect communication faults between itself and adjacent devices.
Therefore, it can take actions immediately to ensure normal transmission of services.

2
Raisecom(config)#bfd session-id
bind peer-ip ip-address
[ source-ip ]
Create a BFD session detection
multi-hop IP path, and enter BFD
session configuration mode.
Raisecom(config)#bfd session-id
bind { peer-ip ip-address }
interface interface-type
interface-number
Create a static BFD session, detect
the single-hop IP path, and enter
BFD session mode.
