Hello everyone! This is my first post here, so please be gentle
. So I've been studying for my CCNA (ICDN 1 and 2 route) for about a little less than a week. I have my own lab set-up consisting of 3x1841, 2x2590 and 1x3550, and I'm running to an issue. So I have PC1 and PC2 connected to switch 1 which is a 2950 on ports fa0/1 and fa0/2 in VLAN 10 & 20 respectively. I'm using a subnet mask of 255.255.255.252. So Pc1 is 192.168.10.1 with a default gateway of 192.168.10.2 and PC 2 is 192.168.10.5 with default gateway 192.168.10.6. The switch is then connected to the router via trunking fa0/15 to the router on fa0/0. I then configured sub-interfaces fa0/0.10 and fa0/0.20 on the router using 192.168.10.2/30 and 192.168.10.4/30, both using dot1q. Now the problem is that both PC's can ping their default gateways. but fail to ping each other. I then enabled EIGRP, but the issue thet hosts still cannot ping each other. Heres the running config of the router:
