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 Jaroslav Aster 2015-07-20 15:19:50 UTC 
Description of problem:

Hi,

I tried to configure vti tunnel on current rhel-7, but iproute is not able to configure [io]key, it fails with error. If I try it without [io]key than interface is created, but tunnel does not work.


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

iproute-3.10.0-46.el7


How reproducible:

100%

Steps to Reproduce:
1. with [io]key

# ip tunnel add Test mode vti remote 1.1.1.1 key 15
Keys are not allowed with ipip and sit tunnels


2. with key

A:

# ip tunnel add Test mode vti local 10.34.36.99 remote 10.34.59.74
# ip a add 172.29.1.1/24 dev Test
# ip l set dev Test up
# ip -d l show dev Test
55: Test@NONE: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT 
    link/ipip 10.34.36.99 peer 10.34.59.74 promiscuity 0 
    vti remote 10.34.59.74 local 10.34.36.99 ikey 0.0.0.0 okey 0.0.0.0 addrgenmode eui64

B:

# ip tunnel add Test mode vti remote 10.34.36.99 local 10.34.59.74
# ip addr add 172.29.1.2/24 dev Test
# ip l set dev Test up
56: Test@NONE: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT 
    link/ipip 10.34.59.74 peer 10.34.36.99 promiscuity 0 
    vti remote 10.34.36.99 local 10.34.59.74 ikey 0.0.0.0 okey 0.0.0.0 addrgenmode eui64

A:

# ping 172.29.1.2

Additional info:

There is second issue, documentation. There is no mention about vti in ip-tunnel manpage.
