RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Serafin Rusu 2019-03-21 21:26:33 UTC 
Description of problem:
I wanted to create a ifcfg config file for a ip6gre tunnel.
I searched in network-functions and ifup-tunnel for a way to configure and I didn't find anything. After research I realized it was not yet implemented. So I want to help you to add this feature.

Version-Release number of selected component (if applicable):
initscripts-9.49.46-1.el7.x86_64


How reproducible:
try to create a ifcfg file for ip6gre tunnel

Steps to Reproduce:
1.
2.
3.

Actual results:
not implemented

Expected results:
use GRE6 as type in ifcfg file

Additional info:

I'm using config file like this:

DEVICE=home6
BOOTPROTO=none
ONBOOT=yes
TYPE=GRE6
PEER_INNER_IPADDR=10.86.0.42 # yes I know, I just want to transport ipv4 on ipv6 only server :)
MY_INNER_IPADDR=10.86.0.41
PEER_OUTER_IPADDR=2a02:f6e2:f030:2328:5a2:872:71d8:3125
MY_OUTER_IPADDR=2a02:3fcd:7ba6:5b8b:cf90:57e3:a715:6464

Could you first submit that as a pull request to:
https://github.com/fedora-sysv/initscripts
Comment 5 Jan Macku 2019-07-10 08:39:47 UTC 
I can build package with suggested changes, but I don't have infrastructure to fully test it.

Would you mind to test it, before it goes to dist git? Thank you.
Comment 6 Serafin Rusu 2019-07-10 09:01:48 UTC 
Sure
Comment 7 Jan Macku 2019-07-11 12:31:39 UTC 
There is initscripts-9.49.46-1.el7.x86_64 package with added option for ipv6 GRE tunnel:

https://fedorapeople.org/~jamacku/initscripts-9.49.46-1-ip6gre.zip

Please be aware that this is testing build and Red Hat doesn't support it.

Please could you test it and let me know? Thank you.
Comment 8 Serafin Rusu 2019-07-26 22:55:48 UTC 
I checked the files form zip but It seems like the patch was not applied.

the files sysconfig/network-scripts/ifup-tunnel and sysconfig/network-scripts/network-functions does not have GRE6 string
Comment 9 Jan Macku 2019-07-30 10:30:40 UTC 
I did build it again and patch should be applied now. I am sorry for previous build.

New build: https://fedorapeople.org/~jamacku/initscripts-9.49.46-1-ip6gre.zip

Please be aware that this is testing build and Red Hat doesn't support it.

Please could you test it and let me know? Thank you.
Comment 10 Serafin Rusu 2019-08-09 20:31:38 UTC 
Now it's ok.
I just tested and it works fine. 
Thanks!
