Can ping switches on different subnets but not the devices attached

[streetteamcollective]

I'm working through a lab and I'm assuming i missing something obvious. I can ping switch0 from Router 1 but not server0. Same with R2 I can ping switch1 but neither hosts.

Any help appreciated I'm just banging my head against a wall

Hello @streetteamcollective 

First if you check Gateway reachability from Hosts and Servers, you can see that there is an issue on LANs side.

The problem is the configuration on Router's interface facin the Swithes.

You need sub-interface, called Router On A Stick configuration: https://www.ciscopress.com/articles/article.asp?p=3089357&seqNum=5

->You should have something like that:

After that, Host-1R-B can ping its Gateway:

Check ip routing on routers, NAT and Standby (hsrp) IP... this VIP should be the Gateway of Servers. 0-RB...

I let you finish this lab.

My main concern is the ability for anything connected to R1 to ping R2 or anything connected to it. I know theres something wrong between R1 and R2 but I cannot figure it out. I think the ip routes are good but clearly i'm missing something.

I did put the router on a stick configuration on R1and R2  but still can't ping past R1 or R2 on either side.

Hello @streetteamcollective

Start by debugging each LAN side. After each hosts ping their Gateway, start debugging routing step by step, hop by hop.

First, I see wrong default gateway on left side for both PCs and switch; fixing that PCs are ok but not switch1 which cannot ping R2. Routers know about their connected networks so 2 static routes on R1 are not needed.

R1 has also static NAT 192.168.6.11 182.0.0.2 - not sure why or what for?

R2 on right side complains about neighbor EIGRP

%DUAL-5-NBRCHANGE: IP-EIGRP 375: Neighbor 144.2.0.10 (FastEthernet1/0) is up: new adjacency

%DUAL-5-NBRCHANGE: IP-EIGRP 375: Neighbor 144.1.0.10 (FastEthernet0/1) is down: Interface Goodbye received

....that's what I found so far, will add more if time permits

Attached your file with corrections.

Please, check all platforms (Switches/Routers) and verify on your initial lab what is the problems:

- static routing issues

- nat issues

- eigrp issue

- Router On A Stick issues (Server0 side)
