Description Petr Barta 2015-09-28 09:03:01 UTC

Description of problem:

IP address of 127.x.x.x family is not removed from eth interface during ifdown eth

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

initscripts-9.03.49-1.el6.x86_64

How reproducible:

Always

Steps to Reproduce:
1. configure /etc/sysconfig/network-scripts/ifcfg-eth0 with IPADDR=127.x.x.x (any IP from 127.0.0.0/8 will do)
2. ifup eth0
3. Check that the IP is present there:
# ip addr sh eth0
4. ifdown eth0


Actual results:

Address from step 1 is still present on the interface

Expected results:

Address from step 1 is removed from the interface after step 4

Additional info:

ifdown works properly with any (tested) IP ouside of 127.0.0.0/8

I apologize if opening a new bug was not warranted.


Thank you,
