I have internet router with 2 interfaces s0/0 and s0/1 .. Previosly, I have 2 mbps leased line in s0/0 interface. Now i have upgraded 4 mbps leased line .. Now the traffic flowing through s0/1 also.. Now the traffic is flowing through s0/0 and s0/1 interfaces.. routing is done by this command
ip routing 0.0.0.0 0.0.0.0 s0/0
ip routing 0.0.0.0 0.0.0.0 s0/1
How the packet is filtering. Based on what traffic is sent through s0/0 or s0/1. Pls explain..
