Example:Configuring Ethernet CFM on Physical Interfaces
CFMcan be used to monitor the physical link between tworouters. This functionality is
similarto that supported by theIEEE 802.3ah LFM protocol.
NOTE: Theconfigurations in this exampleare only partial examples of
completeand functional router configurations.Do not copy these
configurationsand use them directly on an actual system.
Inthe following example, two routers(Router 1 and Router 2) are connectedby a
point-to-pointGigabit Ethernet link. The link between these two routersis monitored
usingCFM. This is shown in Figure 17 on page 116. The single boundary is a “downmep”
inCFM terminology.
