Re: A PC with two NIC routing problem

ip routing is enabled on the switch.

a new vlan has been added to the layer 3 switch:
int vlan 20
  ip addr 20.20.20.1 255.255.255.0

host20 has its ethernet IP address 20.20.20.20/24 and default gateway
20.20.20.1
host20 can ping 10.10.10.100 but cannot ping 11.11.11.100

Please explain why and show me the solution that all hosts can ping the
linux PC?

Thanks,
Jack
