I NEED HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[williamadams52100688]

its probably  a real simple  thing this is my network setup, i have  setup with packet tracer the lab as follows but for the life cant get R1 to ping R4 and vice versa, i have looked at and tried the wildcard route thing 0.0.0.0 0.0.0.0 and still no luck even with the next hop added at the end. please give me some insight and tell me what im doing wrong. ty

Hi

On R1 you need a route toward 10.3.3.0/24 pointing to R2.
You also need the same route on R2 pointing to R3.
On R4 you need the same route as R3 toward 10.1.1.0/24 pointing to R3.

Hi @williamadams52100688 ,

If you want full connectivity between routers, you must ensure that they have a route to all the networks of your topology.
If this network is not directly connected, then you can create a static route for that network.

R1

10.1.1.0 255.255.255.0 connected

need static routes for 10.2.2.0 and 10.3.3.0

ip route 10.2.2.0 255.255.255.0 10.1.1.2

ip route 10.3.3.0 255.255.255.0 10.1.1.2

R2

10.1.1.0 255.255.255.0 connected

10.2.2.0 255.255.255.0 connected

need static route for 10.3.3.0

ip route 10.3.3.0 255.255.255.0 10.2.2.3

R3

10.2.2.0 255.255.255.0 connected

10.3.3.0 255.255.255.0 connected

need static route for 10.1.1.0

ip route 10.1.1.0 255.255.255.0 10.2.2.2

R4

10.3.3.0 255.255.255.0 connected

need static route for 10.1.1.0 and 10.2.2.0

ip route 10.1.1.0 255.255.255.0 10.3.3.3

ip route 10.2.2.0 255.255.255.0 10.3.3.3

i did it that way still not able to ping r1-r4

Hello
Static routing is very administrate to look after especially when your dealing with multiple rtrs in between first hop/last hop rtrs.

Using static routing the most simplistic way would be to apply default routes on R1/4 ( thats only if they dont connect to any other rtr other then what in your topology.

Static routing:
r1-  ip route 0.0.0.0  0.0.0.0 fa0/0 10.1.1.2
r4-  ip route 0.0.0.0  0.0.0.0 fa0/0 10.1.3.3
r2 -  ip route 10.3.3.0 255.255.255.0 10.2.2.3
r3 - ip route 10.1.1.0 255.255.255.0 10.2.2.2

However a better way would introduce a dynamic routing protocol which would be much easier to apply and administer.

Rip: < all routers>
router rip
version 2
no auto-summary
network 10.0.0.0

Eigrp:
r1
router eigrp 100
no auto-summary
network 10.1.1.1 0.0.0.0

r2
router eigrp 100
no auto-summary
network 10.1.1.2 0.0.0.0
network 10.2.2.2 0.0.0.0

r3
router eigrp 100
no auto-summary
network 10.2.2.3 0.0.0.0
network 10.3.3.3 0.0.0.0

r4
router eigrp 100
no auto-summary
network 10.3.3.4 0.0.0.0

ospf:
r1
router ospf 1
network 10.1.1.1 0.0.0.0 area 0
r2

network 10.1.1.2 0.0.0.0 area 0
network 10.2.2.2 0.0.0.0 area 0
r3

network 10.2.2.3 0.0.0.0 area 0

i kinda thru watching Chris Bryant, know or knew that dynamic is way more efficient but im curious as to why this (my initial setup was not working(plus this was the way the lab was setup), can you explain if you have a minute, because with a static route On R1 And R3 i was able to ping at least 3 routers but not the 4th, curious as to y i could not ping the last 1 R4, and any good training materials or courses do you suggest?

Hi,

Try with below configuration:

R1:
ip route 10.2.2.2 255.255.255.0 10.1.1.2
IP route 10.3.3.0 255.255.255.0 10.1.1.2

R2:
Ip route 10.3.3.0 255.255.255.0 10.2.2.3

R3:
ip route 10.1.1.0 255.255.255.0 10.2.2.2

R4:
Ip route 10.1.1.0 255.255.255.0 10.3.3.3
ip route 10.2.2.0 255.255.255.0 10.3.3.3

The reason being that:

R1-R2 didn't have any route to R4
R3-R4 didn't have aby route to R1

Hello,

post your Packet Tracer project (.pkt) file, ZIP it first, otherwise the system won't let you upload it...

[williamadams52100688]

here is my lab setup, and ty to all who responded back so promptly

[williamadams52100688]

Ty @paul driver  for explaining y the routes where unable able to reach each other and to @Deepak Kumar  for the setup that i was further able to go over and get a better overall better comprehension of this static routing thing... wonteven tell you how long i been working on this lab.

truly greatful!
P.S
my finished lab attached which pings r1-r4 and vice versa
