1IP Service PanoramaThe IP services supported by the U2000 are the tunnel, L3VPN, VPLS, PWE3, aggregation, and

composite services.

NOTE

l NEs supporting different IP services are different. "" indicates that the device supports this service

on the U2000. "-" indicates that the device does not support this service on the U2000.

Configure

BFD.

Bidirectional

ForwardingDetection for BFD

is a universal

mechanism used to

detect

communication

faults between

forwarding

engines. To be

specific, BFD

detects the

connectivity of a

data protocol on the

same path between

two systems. The

path can be a

physical link, a

logical link, or a

tunnel. BFD can be

regarded as a

service provided by

the system. The

upper-layer

applicationsprovide BFD

parameters such as

detection address

and detection time.

BFD creates,

deletes, or modifies

BFD sessions based

on these

information and

informs the upper-

layer applications

of the session

status. The upper-

layer applications

then determine

whether to take

actions as the BFD

session status

changes.
