network trunking is not working properly

Latest response

HI

i installed REHL6.1. network port is connected to eth0 interface. trunking is enabled on the switch level

i loaded the kernel modules. and created three virtual network adapter eth0.21 , eth0.3 and eth0.8

 

we need to configure three different network with different gateways. after giving gateway entry on these three files, we restarted network. then only one gateway is showing (route -n). that particular network is pining from outside machine.But we need to ping other 2 ip's from outside machine.

 

how can i solve this issue. please check attached network output

 

 

 

Regards,
