not able to route vlan traffic cent os 6.2
Guys I'm having a routing problem with Centos 6.2 actually I can't really determine where it's coming from but it seems like routing whenever I try to ping a host on a different subnet I get destination host unreachable. I have a managed Dell Powerconnect 2816 switch where I've gone in and configured a few vlans I have made port 16 the trunk port. I have that port running to a Centos 6.2 box using an Intel Pro 1000 Dual MT nic below is the base config of my ETH0 and sub interfaces off of ETH0. Also I've already went to /etc/sysctl.conf and enabled forwarding I also ran lsmod and it looks like the 802.1q module is loaded.
