What am I missing?
I've got a verizon fios router (IP 10.1.1.2) acting as DHCP server for network 10.1.1.0/24. I have a route configured: destination: 192.168.10.0/24 and gateway 10.1.1.2.
Connected to a Cisco C2950G all in VLAN1 (to be edited later) distributing the 10.1.1.0/24 network, that connects to an Apple Airport extreme in bridge mode.
A Cisco 2611XM router f0/0 ip 10.1.1.249 connected to the airport extreme listed above. Interface f0/1 ip: 192.168.10.235 and a DHCP server configured on this router for the 192.168.10.0/24 network. Interface 0/1 is connected to a Cisco 3512 also all on VLAN1.
1) Host connected to Cisco 3512 (192.168.10.0/24 network) won't get a default gateway from my router. Why?
2) Host connected to Cisco 3512 (192.168.10.0/24 network) can't ping my Verizon router (10.1.1.2) - I get a "PING: transmit failed. General failure". Why?
3) Host connected to Airport Extreme (10.1.1.18) can ping Cisco 2611XM router f0/0 (10.1.1.249) and f0/1 (192.168.10.235) but cannot ping a host (192.168.10.2) connected to the 192.168.10.0/24 network via Cisco 3512. Why?
4) I can't ping google.com from the switch. Why?

Hello.
Can you post a topology diagram?
If the DHCP server is in a different vlan from where the users are you should have a relay agent to help the users reach the server leasing ip addresses.
What IP address are the users currently getting?
Regards.

Ping Transit Failed is because of routing Loop or bad Routes.

Thanks to those who replied...and yes, my routes were bad.
Instead of the following routes:
ip route 0.0.0.0 0.0.0.0 FastEthernet0/0
ip route 10.1.1.0 255.255.255.0 FastEthernet0/1
ip route 192.168.10.0 255.255.255.0 FastEthernet0/0
I should have had the single static route:
ip route 0.0.0.0 0.0.0.0 10.1.1.2
Q1) I did not have the "default-router" configured in my DHCP pool - why my client wouldn't get a default gateway.
Q2) Answered via proper static route above
Q3) Also attributable to not having a default router configured for the DHCP pool.
And now it works. I hope this helps someone in the future.
