Hi all,

I'm trying to define a default gateway which is not in the deployment
network. It's on an external network where xCAT doesn't provide DHCP
services (use case is deploying login nodes directly connected to an
external network). Is that possible?

That node would be deployed through eth1 (on the "internal" network),
but its default gateway should be on its eth0 interface (on the
"public" network). I tried a bunch of things, but I can only end up
with the default gateway defined on the "internal" net.

I have:

# tabdump networks
#netname,net,mask,mgtifname,gateway,dhcpserver,tftpserver,nameservers,ntpservers,logservers,dynamicrange,staticrange,staticrangeincrement,nodehostname,ddnsdomain,vlanid,domain,comments,disable
"internal","10.210.8.0","255.255.255.128","eth1","10.210.8.1","10.210.8.1",,"10.210.8.1",,,"10.210.8.110-10.210.8.119",,,,,"","internal",,
"public","xxx.xxx.xxx.xxx","255.255.255.128","eth0","yyy.yyy.yyy.yyy",,,"8.8.8.8",,,,,,,,,"mydomain.com",,

# lsdef login | egrep "eth0|eth1|public|internal|nic"
    installnic=eth1
    kcmdline=quiet repo=http://!myipfn!:80/install/centos6.6/x86_64
ks=http://!myipfn!:80/install/autoinst/login ksdevice=eth1 cmdline
console=tty0 console=ttyS1,115200n8r
    nicaliases.eth0=login.mydomain.com
    nicips.eth0=xxx.xxx.xxx.xxx
    nicnetworks.eth1=internal
    nicnetworks.eth0=public
    primarynic=eth1
    postscripts=syslog,remoteshell,syncfiles,confignics -sr

The result is:

# route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.210.8.0      0.0.0.0         255.255.255.128 U     0      0        0 eth1
xxx.xxx.xxx.xxx  0.0.0.0         255.255.255.128 U     0      0        0 eth0
0.0.0.0         10.210.8.1      0.0.0.0         UG    0      0        0 eth1

Since there's no mention of gateway anywhere in /etc/sysconfig, I
assume the default gateway comes from DHCP.

So,my question is: is there a way to specify the default gateway?

Thanks!
