EIGRP route need help

mindzfreak

Hey guys, why cant i ping from pc4 to server1 ? and also, when i configure eigrp on the R1 (network 10.10.10.0) after that i type in "Show ip eigrp nei" it only shows the 210.1.1.2 why it didnt show 10.10.10.2 since i've already configure (network 10.10.10.0) on it already. Here's the file.

Phase Test practice 2.pkt

Many of the issues associated with EIGRP that can arise are usually related to neighbor relationships or lack there of. Make sure that both routers have formed neighbor relationships, if not start troubleshooting to see why they are not neighbors. Make sure both EIGRP routers have the same AS number, the interfaces advertised are in the same subnet, etc.

show ip eigrp neighbor
show ip eigrp topology
show ip route
show ip interfaces
debug eigrp packets

Usually using the above show/debug commands will yield the reason why the neighbor relationship has not been formed!

Tried all the above. But outcome is still the same Pc4 just couldn't ping to the Server1. Any help?

Its not an EIGRP problem. You didn't put a default gateway on the server so it doesn't know where to send the ping replies. Add the ip for R1 F0/0 as the gateway and pings are successful from PC4 to server1.

Okay, now i've put in the default gateway on the server and ip address for R1 fa0/0 as the gateway. But no idea why it's still unable ping from PC4 to server1. Here : Phase Test practice.pkt.

I've no idea why i've already put in the gateway and everything but still unable to ping

hmm...
Using your .PKT file, all I did was add the correct gateway information to server1 and I can ping fro PC4 to server1 with no issues. Also, is there any particular reason why you are expecting a server that knows absolutely nothing about EIGRP to show up as an EIGRP neighbor in your router?

BTW, that gateway address is 10.10.10.1.

Yea the gateway address is 10.10.10.1. But i just couldnt ping without knowing why. When i send PDU from PC4 to Server1, it can travel successfully untill the part where the PDU reached Server1 and it tries to send back to PC4 it failed. Why

I just took a quick look, R1 doesn't know how to get back to PC4, there's no route in R1's routing table back to the 40.40.40 subnet...

This is R1's routing table:

Gateway of last resort is not set

1.0.0.0/24 is subnetted, 1 subnets
C 1.1.1.0 is directly connected, FastEthernet0/1
2.0.0.0/24 is subnetted, 1 subnets
O E2 2.2.2.0 [110/20] via 1.1.1.3, 00:04:40, FastEthernet0/1
10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
D 10.0.0.0/8 is a summary, 00:05:31, Null0
C 10.10.10.0/24 is directly connected, FastEthernet0/0
20.0.0.0/24 is subnetted, 1 subnets
O 20.20.20.0 [110/2] via 1.1.1.1, 00:04:40, FastEthernet0/1
D 30.0.0.0/8 [90/2172416] via 210.1.1.2, 00:05:24, Serial0/0/0

I have to configured the routing (eigrp/ospf/rip/etc) base on the topology. So i cant randomly use this and that. But then again, i've already configured what needs to be configured already.. so it shouldn't be a problem..since both pc1 and pc2 are able to ping to server1. I just don't know why PC4 just couldn't ping to server1....Any idea.. ?

mindfreakz,

I'm not sure what changes you've made between your posts, currently comparing router configs on R1 and R3. If I use your original file (phase test practice2.pkt -- linked in 1st post of this topic), add the default gateway to server1, I can ping from PC4 with no problems. If I use any of the later versions of the file you have linked, then adding the gateway doesn't solve the problem.

Found it. In "Phase Test Practice 2.pkt" router 1 (named router) you're running RIP version 2. In "Phase Test Practice.pkt" router 1 (named router) is running RIP version 1. It's not sharing the 40 network with R3.

It's true...so some other config must have changed since the 1st post!

But if i'm not wrong, i think i configured Eigrp route on router 1 uh i dont think its Rip ver1 nor ver2 uh..?
