Hi
The above task asks from R4 and R5 routers in a back to back connection to
be configured to use ip addresses 167.x.45.4/32 and 167.x.45.5/32
respectively. Static routing not allowed, additional interfaces allowed.
Initial configurations have encapsulation frame-relay on the affected serial
interfaces.
The solution guide creates loopback interfaces and ip unnumbered to these
loopbacks on the serial interfaces. It then changes the serial interface
encapsulation to ppp.
The lab instructions forbid the change of initial encapsulation types unless
explicitly allowed. I therefore opted to do the following
1. Place the IP addresses on loopback 1 interfaces
2. Create virtual template interfaces with ip unnumbered to the loopback 1
interfaces
3. PPPoFR on the serial interfaces, thus retaining the original
encapsulation.
What would have been the appropriate solution in a real lab? Would any of
you have done it differently? What other ways are there to achieve the task
requirement?
