So I've done the above and the node I have quagga 0.99.5 running on is up 
and talking to everyone fine, routing table looks good.  The only thing 
I'm seeing from zebra in the logs are a few of these (maybe 4x in 
~20hrs) in /var/log/daemon:

Apr 25 10:17:02 cuw zebra[1871]: write : Too many references: can't splice (59)
Apr 25 10:17:05 cuw zebra[1871]: write : Too many references: can't splice (59)

Google tells me this is the ETOOMANYREFS unix error code, but that's all I got.

Dave, in extern-src/quagga/lib/ on the quagga-zrib-update branch there are 
some new route_types.* files.  The .h file is generated using gawk from 
the route_types.txt file.  There are some comments in route_types.txt 
about "switching on redist support" for HSLS.  I'm not sure what this 
means, but I tried compiling/running with it as-is and with the attached 
patch and didn't notice any difference.  Should the the patch be applied?

Bill
