Hello, I'm taking ccna network fundamentals and I'm having a little trouble with configuring the static route on the R1-ISP. I configured the R2-Central static route as; network: 0.0.0.0 subnet: 0.0.0.0 and next hop as 192.168.23.122

I tried configuring the R1-ISP as 0.0.0.0, 0.0.0.0, and 192.168.23.121 but that did not work. I then tried 192.168.23.122, 255.255.255.255, and 192.168.23.121. It added it without saying "invalid IP address" or "inconsistent address and mask" What am I doing wrong?

I'm stuck at 97% on this pt, any help would be appreciated.

Why dont you post the whole config of both routers?

Oh yeah, R-1 ISP's fast ethernet 0/0 has an IP address of 192.168.23.110 and a subnet mask of 255.255.255.240 and the serial 0/0/0 has an IP address of 192.168.23.122 and subnet mask 255.255.255.252 and is connected via a serial DCE cable to R2-Central with a fast ethernet0/1 IP address of 192.168.23.62 and subnet mask of 255.255.255.192 and the serial0/0/0 has an IP address of 192.168.23.121 and a subnet mask of 255.255.255.252

Again, post the config and what you are trying to accomplish.

I am trying to implement a standard lab topology with a new IP addressing scheme.

You have been given an IP address block of 192.168.23.0 /24. You must provide for existing networks as well as future growth.

Subnet assignments are (assuming ip subnet-zero is enabled):
1st subnet, existing student LAN (off of router R2-Central), up to 60 hosts;
2nd subnet, future student LAN, up to 28 hosts;
3rd subnet, existing ISP LAN, up to 12 hosts;
4th subnet, future ISP LAN, up to 6 hosts;
5th subnet, existing WAN, point-to-point link;
6th subnet, future WAN, point-to-point link;
7th subnet, future WAN, point-to-point link.

Interface IP addresses:

For the server, configure the second highest usable IP address on the existing ISP LAN subnet.
For R1-ISP's Fa0/0 interface, configure the highest usable IP address on the existing ISP LAN subnet.
For R1-ISP's S0/0/0 interface, configure the highest usable address on the existing WAN subnet.
For R2-Central's S0/0/0 interface, use the lowest usable address on the existing WAN subnet.
For R2-Central's Fa0/0 interface, use the highest usable address on the existing student LAN subnet.
For hosts 1A and 1B, use the first 2 IP addresses (two lowest usable addresses) on the existing student LAN subnet.
Additional configurations:
For PCs 1A and 1B, in addition to IP and default gateway configuration, configure them to use DNS services.
For the server, in addition to IP and default gateway configuration, enable DNS services, use the domain name eagle-server.example.com, and enable HTTP services.
For R1-ISP router serial interface, you will need to set the clock rate (a timing mechanism required on the DCE end of serial links) to 64000.
No clock rate is needed on the DTE side, in this case R2-Central's serial interface.
Task 2: Finish building the network in Packet Tracer

Add cables where missing.
Connect a serial DCE cable to R1-ISP S0/0/0, with the other end to R2-Central S0/0/0.
Connect PC 1A to the first FastEthernet port on switch S1-Central.
Connect PC 1B to the second FastEthernet port on switch S1-Central.
Connect interface Fa0/0 on router R2-Central to the highest FastEthernet port on switch S1-Central.
Connect interface Fa0/0 on router R1-ISP to Eagle-Server.
For all devices, make sure the power is on to the device and the interfaces.
Task 3: Configure the Network

You will need to configure the server, both routers, and the two PCs. You will not need to configure the switch nor do you need the IOS CLI to configure the routers. Part of the router configuration has already been done for you; all you must do is configure the static routes and the interfaces via the GUI; use 64000 as the clock rate on the serial link. The static route on R1-ISP should point to the existing student LAN subnet via R2-Central's serial interface IP address; the static route on R2-Central should be a default static route which points via R1-ISP's serial interface IP address.

I have done every configuration listed above but I am stuck at trying to configure the static route on the R1-ISP router.

I've attached a screenshot of what I have in packet tracer.

Lol I think he means type show running-config and paste it here.

I uploaded two documents containing the running config info.

ip route 0.0.0.0 0.0.0.0 192.168.32.121 doesn't work?

Try "ip route 0.0.0.0 0.0.0.0 serial 0/0/0" instead.

Hmm... 0.0.0.0 0.0.0.0 serial 0/0/0 for the static route to R2-central doesn't work either.

Do you have ping to the IP 192.168.32.121 from R1?

I just pinged it from the R1-ISP router. Here is a screenshot of what it says.

Are you doing some of that PT works wich grade you based in what you have done?



You should have ping to the host, may be you need the route asked in the homework.

Try "ip route LAN subnet Mask 192.168.32.121"

The above input means " ip route 192.168.23.0 255.255.255.192 192.168.32.121"

Ok. The default route should work, if do you want to ping to a host see if the host has a default gateway configured.

The host has a default gateway of 192.168.23.110

I pinged that from the R1-ISP and it said that the success rate was 100 percent.

Also, here is a screenshot of the grading in the activity results. I'm just having trouble figuring out what I need to input for the network address, subnet mask, and next hop for the static route.

Oh wait that 192.168.23.0 255.255.255.192 192.168.23.121 worked! Thank you very much for all of your help! No wonder why what I was imputing didn't work. I was imputing 192.168.23.122 or 0.0.0.0 for the network address.

A default route worked(you had connectivity to the hosts) but the activity asked for a specific static route, not a default route. You should study again the routing stuff.

Yes I definitely should study routing more. Again, thank you for your help.

You configured a default route on R2-Central, but you didnt configure a route back in R1-ISP. If you dont configure a route in ISP router, the server wont be able to reach the computer. However, you will be able to ping between the routers as they are directly connected. I dont know if you got my point, if not I can elaborate it more if you want.

About the lab, I think you were supposed to make a normal static route, not a default one, or maybe just complete the route in the R1-ISP.

I configured follow to above. It's still not work. It's 95%.

I checked the topology and the routes are well configured. PT bug?
