Why need "ip routing"??

[JustTakeTheFirstStep]

I can hardly understand.

Ping test from PC to WLC failed.

Same network.

Same VLAN.

The ping was successful only after "ip routing" in SW.

Why the hell need routing??

Hello,

looking at the fact that you have several interfaces with IP addresses:

interface Vlan1
ip address 172.29.22.1 255.255.255.0
no ip route-cache
!
interface Vlan50
ip address 172.29.26.1 255.255.255.0
no ip route-cache

!

interface GigabitEthernet1/0/2
no switchport
ip address 1.1.1.1 255.255.255.0
no ip route-cache

Disable 'ip routing', delete interface Vlan 50, convert interface GigabitEthernet1/0/2 to a switchport, and try again.
