I have a 2900 switch connected to 1700 series router. The router is configured as router on a stick with multiple DHCP pools, so the port connected to the switch is a trunk port at both end.
Hosts connected to the switch are able to grab dhcp address on their respestives vlan. Howver, from the switch ip I cannot ping the router and from the router I cannot ping the switch. For this example, let say that the IP is 10.0.0.0/24, 10.0.0.1 is the router IP address and 10.0.0.2 is the switch. I did add ip default-gateway 10.0.0.1 on the switch. But it still cannot ping 10.0.0.1.
Any ideas is more than welcome.
