Experimental questions
It is the same as the comprehensive experiment of static routing (see the "IP address planning" of my blog HCIA static routing comprehensive experiment for details ). The first is the planning of the IP address. According to the analysis, a total of 4 network segments are needed, as follows
192.168.1.0/26 — The backbone network segment connecting R1 and R2
192.168.1.64/26 — The backbone network segment connecting R2 and R3
192.168.1.128/26 — R1
192.168.1.192/26 — R2
Among them, R1 and R2 need to be divided into two network segments for the "loopback" required in question 2.
192.168.1.128/26 — R1 192.168.128/27 192.168.160/27
192.168.1.192/26 — R2 192.168.192/27 192.168.224/27
The final result is as follows
