Description Fotios Tsiadimos 2016-09-16 20:26:01 UTC 
Description of problem:
satellite 6 provisioning a client with 2 nics will have to default gateways.


Version-Release number of selected component (if applicable):

Satelltie 6.2.2

How reproducible:

Create 2 subnets on the Satellite and specify the gateway for etch one then create a client and add 2 networks to point to these 2 subnets. After you kickstart the client the client will have 2 default gateways. when we create a new host we need to have an option to specify the default gateway instead to remove the gateway from the subnets.

Comment 18 daniel 2017-09-27 15:50:26 UTC 
In case one has 2 subnets configured with 2 gateways we really get 2 default gateways configured:

cloned kickstart_networking_setup to kickstart_networking_setup2 and changed it as suggested by https://bugzilla.redhat.com/show_bug.cgi?id=1376924 / http://projects.theforeman.org/issues/18125  , also cloned default kickstart template and added the new snippet there (renaming kickstart_networking_setup to kickstart_networking_setup2 and associated this to the OS,
redeployed host:
