In case you were, like me, wondering what this was about Sun, 12 Mar 2006 19:45:00 GMT donotreply@osnews.com (Ronald Vos) Comments http://osnews.com/thread?103710 http://osnews.com/thread?103710 Quagga's or Zebras CLI is borrowed from Cisco, this means that all Cisco's is hard and incovinient to configure too :-) I don't agree. Besides quagga includes RIP, OSPF and BGP daemons. OpenBGPd is a single daemon.

Cisco's IOS is disgusting to use, so yeah, Quagga's is.
And OpenBGPd comes with OpenOSPFd, the OSPF and RIP handling daemon.

Because they're related and useful with one another.

The RFC allow it but I didn't manage to do it: the configuration is not easy..

And the hard truth is that zebra suck: I know I'm using it and I've seen:
-stupid timer management: if you update the date in the past, zebra's rip daemon will stop sending periodic route annonces, nice huh?
-memory leak (if you change the configuration of ripd and send it a SIGHUP to make it reread its configuration, sometimes it remembers the old configuration..).
-core dumps

I haven't tried Quagga but configuration in quagga doesn't seem better explained that in zebra though. Sun, 12 Mar 2006 23:19:00 GMT donotreply@osnews.com (renox) Comments http://osnews.com/thread?103892 http://osnews.com/thread?103892 "Why it's name OpenBGPd if it includes OSPF anr RIP?"

Because it doesnt? OpenBGPD includes bgp tools, nothing else. Open*BSD* on the other hand does include both OSPF and RIP.

I find the IOS (and Zebra/Quagga) interface to be a royal pain in the butt to work with. They're pretty much the worst interfaces ever designed.

"Besides quagga includes RIP, OSPF and BGP daemons. OpenBGPd is a single daemon."
Do you have a point other than stating the obvious?

Mon, 13 Mar 2006 09:13:00 GMT donotreply@osnews.com (renox) Comments http://osnews.com/thread?103970 http://osnews.com/thread?103970 Sorry maybe I wasn't clear enough: in RIP by default the source IP address used to broadcast a route is the gateway, but when there are several IP address on a given interface sometimes it can be difficult to be sure that the route is broadcast with the IP address you want.
But in RIPv2, you can broadcast a route specifying the IP address of the gateway, but I haven't managed to do it, documentation of zebra is a bit incomplete in my opinion (this plus the other flaw mentioned, I can understand why someone started a different progress..).

As I know RIPv1 broadcast entire routing table, not a single route. RIPV2 sends routing table unicast or multicast. If you have several IP adresses on a given interface use RIPv2 and send routing table to one or more neighbours neighbors:
router rip
neighbor 10.10.10.10

You can publish a route with a specific gateway IP address in the RIPv2 protocol ie you don't only say "I know a route towards the subnet X with a cost C" but "the gateway GW know a route towards the subnet X with a cost C".

How do I put the gateway GW in the ripd configuration file?

It's not clear at all from zebra's documentation.

If an orange is called an orange, is it insulting?
I don't particularly find those situations insulting, but it insults my intelligence for you to pretend that my correct words are inappropriate because I called a retard a retard.
I saw a man call an apple an orange and I called him a retard for it, if you don't like it, feel free to ignore it, but I don't see it as an insult to call John Edward MaGee, Jr. a giant talking douche for his obvious taking advantage of simple minded people, nor do I see it as one to call eazy a retard for failing to read.
If you invalidate a point because it is made in a manner you don't like, you're going to really hate Penn and Teller's Bullshit and you're going to end up not listening to jack shit all, because noones ever going to talk to you.

You don't know anything about the OpenBSD crowd do you? A slightly thicker skin is required, but they rarely get nasty unless they are actually correct.

That doesn't mean I just "tolerate" it and let it slide because "they rarely get nasty unless they are actually correct." As per my first post, I agreed with the sentiment, just not the method of delivery. Standing by and letting people act like asses to others really isn't a moral choice as far as I'm concerned. I'm not the police, but I'm not going to sit by and watch somebody get a +5 for a post that consists of 90% insulting/abrasive language, and 10% information, when it is specifically a reason to down-moderate posts for abusive language.
