I have setup a Linux machine on my server but for some reason Im unable to reach my default gateway. This is causing me to not communicate with the outside world (unable to connect to CentOS repos)
Now the default gateway here is 142.133.48.1 and it falls under my network.
But I cannot ping it.
Firewall and iptables is off. So I have no idea what else might be wrong here.
We are unable to bring one of our linux boxes into the network once it was restarted. But once we stop and start the network service. We are able to ping the gateway and get into network. After a minute or two we get the following reponse for the ping command

Hi,
I installed AIX 7.1 on a blade though (hmc with vio). I can ping the IP address, but not the gateway. Is there anything that I should configure?

vde_l3
VDE_L3(1) General Commands Manual VDE_L3(1)NAME
vde_l3 - Virtual Distributed Ethernet 'Layer 3' Switch.
SYNOPSIS
vde_l3 -v vde_plug:ipaddress/netmask [-v...] [-r target_network/netmask:gateway] [-G default_gw] [-M mgmt_socket]
DESCRIPTION
A vde_l3 connects to one or more vde_switches, performing ip forwarding among its virtual interfaces. A new interface is created at startup
for each -v option given at command line. Static routes to target networks can be defined using the -r option.
vde_l3 -v /var/run/s1.ctl:192.168.0.1/24
connects to the vde sock at /var/run/s1.ctl with its virtual interface ve0, having the address 192.168.0.1 and netmask 255.255.255.0.
vde_l3
-v /var/run/s1.ctl:192.168.0.1/24
-v /var/run/s2.ctl:10.0.0.254/255.255.0.0
connects to the two vde socks, with its virtual interfaces ve0 and ve1, having addressess 192.168.1.0 and 10.0.0.254 respectively. Hosts in
each network can specify the vde_l3 as their gateway to reach the other one.
OPTIONS -v vde_plug:ipaddress/netmask
Creates a virtual network interfaces on the vde_l3 box, with address ipaddress and netmask netmask. Please note that the netmask can
be specified either in the 'classic' A.B.C.D mode, or just by giving the number of leading bits (f.e., /17 for 255.255.128.0). One
can define as many interfaces as she wants.
-r target_network/netmask:gateway
Specify a static route through gateway to reach hosts in target_network with netmask netmask. One can define as many routes as she
wants.
-G default_gw
Specify a default gateway, to be used whenever no static route is defined for a target host.
-M mgmt_socket
the unix socket where the parameters (interfaces addresses, routes, etc.) can be checked and changed runtime. unixterm(1) can be
used as a remote terminal for wirefilter.
