Ccnp - basic l3 switch routing issue

samuel.lao85

Hi guys,

Im studying CCNP SWITCH. I was checking IP CEF features, so I decided to start using 3550 Catalyst switch in order to do InterVlan Routing (VLAN 1 and VLAN 2). Here is my info

SW1925_Internet#

But, I still can't route traffic between those VLANS. Both VLANS show LINE UP, PROTOCOL UP, but there is only routing in 1 direction.

Ping from 172.16.1.5 ---> 192.168.1.25 works
Ping from 192.168.1.25 ---> 172.16.1.5 not working

Additionally, the same happens if you try to use ping within the catalyst.

I would appreciate your advices....
