Cisco Packet Tracer - Can't make communication between routers

[fb_webuser]

Hi,

I have problem:

I have to create 4 routers with mask /30 and 2 switches that will be assigning IP addresses with mask /24 and /25, well, I'm using cisco packet tracer for this simulation

I've already created 2 basic routers, each is connected to one switch, and to each switch I have connected 2 PCs, communication between them works fine, I've tested it with ping between PCs and to router

so I have 2 routers, 2 switches and 4 PCs

R1

R2

SW1

SW2

PC1-4

-

---

Connection:

R1 - SW1 - PC1 & PC2

R2 - SW2 - PC3 & PC4

-

---

first router is using 192.168.1.1/30

PCs are 192.168.1.2/24 and 192.168.1.3/24

-

---

second router is using 192.168.2.1/30

PCs are 192.168.2.2/25 and 192.168.2.3/25

-

---

now I have to ADD 2 more routers and make communation between all 4

--- this is where I'm having troubles

so I created another 2 routers, added serial ports (module) to ALL routers

so now I have 4 routers with 2 serial ports EACH

R1

R2

R3

R4

R1 and R2 are described above

-

connections;

R1s0 - 192.168.3.1/30

R3s0 - 192.168.3.2/30

R2s0 - 192.168.4.1/30

R4s0 - 192.168.4.2/30

R3s1 - 192.168.5.1/30

R4s1 - 192.168.5.2/30

here is Cisco Packet Tracer project to make it easier: http://www.sendspace.com/file/jh2q8o

I'm trying to figure out what's wrong for about 4 hours now but without luck...

Hi,

first configure clock rate on all your DCE interfaces: s0/1/0 on R15, s0/1/1 on R24 and s0/1/0 on R17

Then enable RIP v2 to have full connectivity:

just paste this in config mode on all routers:

router rip

ver 2

no au

netw 192.168.1.0

netw 192.168.2.0

netw 192.168.3.0

netw 192.168.4.0

netw 192.168.5.0

passive f0/0

Don't forget to rate if helpful.

Regards.

thanks, I just have 2 more problems -

which clock rate do I need to configure (I'm just learning this - CCNA Network Fundamentals on High School)

and I can't somehow do anything in CLI of r23

edit: well now I can write to CLI of r23, but when I use "router rip" command i'm getting this:

^

% Invalid input detected at '^' marker.

+ what about those clock rates?

Hi,

you can use clock rate 64000 for example( or any other one you want) as here it is only for making the line protocol up.

router rip must be entered in config mode and you need to make sure you have ip routing enabled( which is default) by issuing sh ip route and you'll see connected routes.

thanks again, I've did everything but I still can't ping 192.168.2.2 from 192.168.1.2

-request timed out

the project is here: http://www.sendspace.com/file/kxebjv

maybe u can take a look on this cuz I really have no idea where's the problem

Hi,

The ping is working correctly. You may wait for ARP reply before getting first successful ping though.
