Hi Fellow Techies,
I've been trying to tackle this problem for 2 weeks or so and it has become irritating finally I thought i should get your thoughts on this problem. What am i missing ?
This is part of my homelab infrastructure.
InterVLAN routing is working flawlessly, meaning i can ping all vlans and its hosts.The problem is that i can't reach the router 192.168.1.254 from any of my VLANs, though i can reach 192.168.1.1 which is the routed interface (Fe 0/15) on Layer 3 switch.Furthermore i can reach 192.168.1.254 from the layer 3 switch but not from the VLANs
Here is the config from 3550 L3 switch
isis#sho run Building configuration...

I can reach my file server pegasus from my workstation saber, and i can reach deadalus which is my ESXi server from saber as well, meaning InterVLAN routing is working.
I've tried equivalent config on Netgear GSM7312 L3gigabit switch and 3COM/HP 4924 L3 gigabit switch and the issue remains unsolved.
Thanks for your support.
