static routing 3 routers dont know how to do it

[bautiarcangeli]

Hello everyone. Thanks for reading. I have to connect the PC 0 to the network of router 3. But, I have to pass through the router 2 (the green path). I dont have to use del above path, the red one. I need to go strictly through router 2. Any idea how to do it? Do i have to use static routing? (my teacher said that i should use it) Thanks in advance.

add adminstrative distance with static route - to prefered route. (if this is only want to with static route)

if IGP used you can add cost to prefered route.

Configure two startic routes in Router1 one via Router2 and another via Router3

Since via Router2 is the required path configure static route with lowest AD (Administrative Distance) through exit port ser0/0/1

Router1(config)# ip route 192.168.101.0 255.255.255.0 ser0/0/1 1

Configure another static route with higher AD through exit port ser0/0/0

Router1(config)# ip route 192.168.101.0 255.255.255.0 ser0/0/0 2

When everything is fine...via Router2 will be best path...In case Router2 down then automatically you can reach via Router3.

Hello @bautiarcangeli,

Yes, use static routes.

R1: 

ip route 192.168.101.0 255.255.255.0 192.168.1.2

ip route 192.168.101.0 255.255.255.0 192.168.2.2 10

R2: 

ip route 192.168.101.0 255.255.255.0 192.168.3.2

ip route 192.168.100.0 255.255.255.0

192.168.1.1

R3:

ip route 192.168.100.0 255.255.255.0 192.168.3.1

ip route 192.168.100.0 255.255.255.0 192.168.2.1 10
