Description Gary A. Ernst 2002-05-15 14:20:26 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv: Gecko/20020314

Description of problem:
Zebra does not update kernel routing table from learned rip v2 updates. show ip
route and show ip rip report the expected routes but route -n does not reflect
learned routes. Additionally, When a tunnel is added via hercules zebra deletes
the default route. zebra and ripd are the only routeing protocl daemons running.

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

How reproducible:

Steps to Reproduce:
1.Start zebra on a network that is known to send multicast ripv2 routes
2.Start ripd on same

Actual Results:  No routes are added

Expected Results:  route command should show same routes as show ip route issued
from zebra vty.

Additional info:

Note The same level of zebra/ripd work fine on a slackware based box at the same
kernel level 2.4.18 and zebra-0.92a

Your best bet for a quick solution is probably to ask upstream - the zebra
mailing list etc.
Comment 2 Gary A. Ernst 2002-05-15 17:27:54 EDT
Have you verified functionality at the given levels ?
Comment 3 Elliot Lee 2002-05-15 17:33:00 EDT
Comment 4 Gary A. Ernst 2002-05-15 18:41:36 EDT
Then what am I supposed to go to the zebra site with ? It works on slackware not
on RedHat ? What suggestions do you suppose I'll get ?
Comment 5 Elliot Lee 2002-05-15 18:50:15 EDT
The zebra site will put you in touch with people who know zebra from the ground
up, and others who may be experiencing the same problem. I can do neither.

I have a similar problem on RH 8.0 beta.  It appears that Zebra 0.92a has a
problem.  Versions 0.91a and 0.93a do not have this problem.  It relates to the
fact that it considers the RIP routes coming from a non-active link, *because*
that link is a kernel route.  We have remade the RH rpm with 0.93a and now it

I have seen this issue with many recent versions myself. Been perplexing trying to
identify root cause, but restarting network and bgpd resolves it every time. Not
a very good work around for a routing daemon.
Comment 8 Ted Kaczmarek 2003-01-25 12:22:38 EST
Forgot to mention with bgp routes :-) And yes I do see them in the bgp table.
