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..

Hello Vinoth,

static routes are unware of your BW upgrade and currently you are load-balancing outbound traffic between the two links.

If you want to use s0/1 as only a backup do the following

conf t

ip route 0.0.0.0 0.0.0.0 s0/1 200

no ip route 0.0.0.0 0.0.0.0 s0/1

end

this way s0/1 will be used only if s0/0 fails

Hope to help

Giuseppe
