Check the manual, etc. I'm not sure whether it is compiled in by default, 
but:

./configure --enable-vtysh

Any reason why not leave them on the default ports (zebra on 2601 and 
bgpd on 2605)?

[zebra 13874] Zebra without any route input?

I am trying to set up a redundant Internet connections for my company.

We have a T1 connection through a 1605R Cisco router. The Cisco routed is 
configured to broadcast RIP.

We also have a wireless connection that I would like to use as the default 
connection for most traffic. Unfortunately, the ISP controls the router and 
they will not give me RIP, or anything else.

Is there some way I can use a ping command or some other discovery method 
along with zebra to manipulate the routing tables so that if the wireless 
connection goes down, the network switches over to using the T1 connection?

Or should I just use a script to directly manipulate the routing tables and 
not bother with Zebra?

Thanks!
Simon

there's a zebra rpm at:

which is what we're using here internally. its CVS + the fixes i
posted a while ago. we've had /no/ crashes since (woohoo!) of
unattended ospfd processes. (there's a crash if you do "no network
...", ospfd.c:610 - havnt fixed that one yet, but hey, dont do it. :)  
).

above is compiled with multipath support, without snmp or mpls-te
support.

i intend to apply the md5 auth patch sometime aswell (that'll be -8).

the bgpd daemon in above seems stable to.

[zebra 13876] Re: Zebra without any route input?


If this box is linux based, you dont need zebra for this. You can use the
iproute2 utils and create different "weighted" default routes, specifying
a greater weight for the wireless connection and a smaller weight for
the T1 connection.

A google search should net you some decent examples.

A quick example using would be:

# T1 = eth1 / 10.2.2.2
# wireless = eth0 / 10.1.1.1

ip route add default nexthop via 10.2.2.2 dev eth1 weight 1 \
		     nexthop via 10.1.1.1 dev eth0 weight 2

This should flow all traffic thru 10.1.1.1 as long as its available, using
10.2.2.2 if its not.

[zebra 13877] RE: Best 'free' routing Daemon for Solaris?

Um, the Zebra site itself uses an 0.X version number.  Unless things
have changed, this nomenclature as generally used in software development
indicates beta software.

There's nothing wrong with having a "no-beta-software-on-production"
policy, but unfortunately as there's no "competition" in the free
routing daemon market, the Zebra maintainer can pretty much get away
with running a continuous beta, and so you are stuck with either
beta software or no software.

I do hope, though, that Zebra reaches version 1.0 before I retire. ;-)

[zebra 13878] RE: Zebra without any route input?


The difficulty with these schemes is determining linkdown state.
Even if you put together a Linux box that has 3 NIC's, one to the
Cisco 1605, one to the wireless bridge, and one to the internal
network, your going to find that neither the wireless bridge
nor the Cisco 1605 will ifconfig down their ethernet interfaces
if their links go down.

Furthermore if the T1 is Frame Relay, you can easily have a
situation where LMI does not go down on the T1 but the Telco
fardles up the PVC, so even if the Cisco router could be configured
to ifconfig down it's interface, the dumb router won't think that
the frame circuit went down.

These are the kinds of links that OSPF is designed for.  Without it
your reduced to ugly scripts that probe remote IP numbers periodically
in an attempt to determine if remote hosts aren't working.

I have found that in every case that the T1 went down, the T1 serial line 
went down so the 1605R stopped broadcasting RIP. My problem is that the 
Wireless connection (which I want to be the primary) does not have any RIP 
or other routes broadcast into my subnet.

Steve,

This is interesting. Is it available on RH 6.2/2.2.x Kernel?

Tell your ISP that you want enable on the router.  Either that or go out
to the Cisco site and look up the appropriate procedure to
"recover" enable access to the cisco.

Once you get that accomplished, you'll be able to configure dynamic
routing protocols and do things properly.

Can anybody know the site (other than official zebra.org) which contains
the latest working patches, which  - i suppose zebra-developpers did not
add to the official version from the unknow reason (maybe other work or
project that zebra devellopers are concentrated on).
