Description of problem:
I upgraded from Red Hat Linux 8.0 to Fedora Core 1. On RH8 I used 
zebra for IPv6 router advertisement. In Fedora the zebra package has 
been replaced by the quagga package, which includes zebra aswell. 
Unfortunately the new zebra isn't able to do broadcast IPv6 router 
advertisements anymore.

Version-Release number of selected component (if applicable):
quagga-0.96.4-0.fc1

How reproducible:
Always

Steps to Reproduce:
1. Configure IPv6 router advertisement in /etc/quagga/zebra.conf:
(...)
interface eth0
 ipv6 address 2001:888:1083:100::1/64
 no ipv6 nd suppress-ra
 ipv6 nd prefix-advertisement 2001:888:1083:100::/64
(...)

2. Reload the zebra configuration:
odie# service zebra reload


Actual Results:  The following messages appear after starting zebra:

Starting zebra: Nothing to flush.
There is no such command.
Error occured during reading below line.
 no ipv6 nd suppress-ra
[FAILED]


Expected Results:  It should not report any error messages regarding 
to IPv6 router advertisement. Also, I should expect to see Router 
Advertisements on my network whenever a new IPv6 host boots.

Additional info:

I found a solution for this downgraded functionality:

I downloaded and installed the quagga source RPM, and added the 
option "--enable-rtadv" to the configure command (lines 105-151 in 
the spec file). After building and installing the RPM the IPv6 router 
advertisement meganism works.
