I m having internet router 2600 series..
Which has 2 mbps leased line circuit.. Recently we have upgraded 2 mpbs to 4mbps.. Now traffic is flowing through both interfaces int s0/0 and s0/1..
which is having static route
ip route 0.0.0.0 0.0.0.0 s0/0
ip route 0.0.0.0 0.0.0.0 s0/1
How traffic is flowing through both interfaces .. Both having static route and administrative distance also same.. when the packet reaches router,how packets forwarded to the interfaces..
