Introduction to Frame Relay Technology
As a CCNA, you’ll charge to accept the basics of the Frame Relay technology and be able
to configure it in simple scenarios. First, accept that Frame Relay is a packet-switched
technology. From aggregate you’ve abstruse so far, aloof cogent you this should accomplish you
immediately apprehend several things about it:
You won’t be application the encapsulation hdlc or encapsulation ppp command to configure
it.
Frame Relay doesn’t assignment like a point-to-point busy band (although it can be fabricated to
look and act like one).
Frame Relay is usually beneath big-ticket than busy curve are, but there are some sacrifices
to accomplish to get that savings.
So, why would you alike accede application Frame Relay? Take a attending at Figure 11.7 to get an
idea of what a arrangement looked like afore Frame Relay.
FIGURE 1 1 . 7 Afore Frame Relay
Now analysis out Figure 11.8. You can see that there’s now alone one affiliation amid the
Corporate router and the Frame Relay switch. That saves some above cash!
If, for example, you had to add seven alien sites to the accumulated appointment and had alone one
free consecutive anchorage on your router, it’s Frame Relay to the rescue! Of course, I should probably
mention that you now additionally accept one distinct point of failure, which is not so good. But Frame
Relay is acclimated to save money, not to accomplish a arrangement added resilient.
Coming up, I’m activity to awning the Frame Relay technology advice you charge to know
about back belief the CCNA objectives.
