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):
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.
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.
Have you verified functionality at the given levels ?
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 ?
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.
Forgot to mention with bgp routes :-) And yes I do see them in the bgp table.
Red Hat Linux 7.3 is no longer supported. If you can reproduce this
