adding up the remote site CIR (128 Kbps + 64 Kbps + 64 Kbps + 64 Kbps = 324 K).
determined that another block of 64 addresses can be used. The address range
199.198.197.65127 with a mask of 255.255.255.192 (or 26, because 26 bits
make the mask) has been determined and is now available for addressing hosts.
The CIR assigned to this site is 128K, which is the most bandwidth of the four
remote sites. Notice that this site has the most users as well.
amount of bandwidth needed on the Frame Relay links. If that rule is applied here, 4 K
multiplied by 40 is 160 K.
CIR, and if that is not enough, it can always increase the CIR later.
Also, this traffic needs to be monitored regularly because network
traffic doubles about every year or year-and-a-half. That has been
consistent for the last six years.
.129 address is being used by the router's Ethernet port. This leaves 130142 as
effective host addresses, or about 12 to use.
145 being assigned to the router's Ethernet port. This leaves 146158 as effective
host addresses, satisfying the requirement for 10 users.
161 being assigned to the Ethernet port. This leaves 162174 as effective host
addresses, satisfying the requirement for 10 users.
mask of 255.255.255.248 (or a 29-bit host mask). Because this example is a multipoint
Frame Relay interface, all IP addresses should be on the same subnet.
