In linux FC9, setting eth0 has default, ping -I eth1 IP address is working fine. In FC14 tehe same does not work. The above check is done to test the connectivity from that interface so that if the default link connectivity goes down, the default gateway will be changed. Please help me.

You need to set up IP multihoming.

Do this:

create secondary routing table:

echo -e "200\tuplink2" >> /etc/iproute2/rt_tables

add second default route to this table

echo "default table uplink2 via GA.TE.WA.Y2" > /etc/sysconfig/network-scripts/route-eth1

create a rule to put traffic source with eth1 ip to uplink2 routing table:

echo "from IP.AD.DR.ES table uplink2" > /etc/sysconfig/network-scripts/rule-eth1

restart networking:

service network restart
