Hi everyone,
I need help on what seems to be simple but driving me crazy.
I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are:
1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN.
2. I noticed that despite the fact that users can get IP address automatically from the switch, they cannot connect to the enterprise network. They can ping only the IP addresses local on the switch, but not any other IP address beyond the switch, although my laptop (ONLY MMY LAPTOP) could connect normally and ping remote IPs.
Could this be a CEF issue? Since CEF is enabled by default???

Please see the “debug ip packet details” and relevant configs attached

Will appreciate your suggestions.

Can you run a 'show vlan' and check that you have created the L2 Vlan for Vlan27.

I can see from the config that you have created a L3 SVI for it but not whether you've created a L2 Vlan.

Try changing this network statement " network 172.27.100.254 0.0.0.0 to network 172.27.100.0 0.0.0.255 .

the description of the issue you are facing isn't too clear to me. Can you explain the issue you are facing possibly with a diagram?

@vipergg
i don't think changing the network statement will affect anything. once the network statement picks any interface that falls in the range, it advertises the subnet as specified on the interface
