无法ping通辅助接口专用IP

Question

I have attached a secondary interface to Debian EC2 instance. I attached the same security group that primary interface has and it allows ping on it. Problem is after attaching the second network interface I am not able to ping the Secondary interface private IP.

eth0      Link encap:Ethernet  HWaddr 0a:65:1c:fd:cd:f0

Ngrep result pinging from other interface:

root@ip-10-195-0-76:/home/admin# ngrep -d eth1 -Wbyline
interface: eth1 (10.195.0.64/255.255.255.224)

Answer 1

Debian in AWS does provide ec2-net-utils but the scripts on EC2 does not add the routes for the secondary interface. To solve this i followed the following to add the routes for the interface.

#echo "200 out" >>/etc/iproute2/rt_tables
# ip route add default via 10.195.0.65 dev eth1 table out
#ip route show table out
#ip rule add from 10.195.0.82/32 table out
#ip rule add to 10.195.0.82/32 table out

And after that i am able ping the network interface.
