Dear, all
1.I want to install ns-3-allinone to join the work with quagga ,how
can i do to install it?
2.I want to study Link State routing protocol such as OSPF in ns-3,
how can i get start?
suggest me , please..
thank

you can try with ns-3-dce-quagga-umip, since it also include
zebra support.
- ns-3-dce-quagga-umip
http://groups.google.com/group/ns-3-users/browse_frm/thread/ea7c71e635254204/b5a7ab7acdda6b29#b5a7ab7acdda6b29
It only works under Ubuntu 10.04 x86_64, so far.
>2.I want to study Link State routing protocol such as OSPF in ns-3,

you can take a look of example at
ns-3-dce-quagga-umip/src/dce/example/quagga.cc
ns-3-dce-quagga-umip/src/dce/example/quagga-rocketfuel.cc

Dear Hajime, all.
I used the great work you did with zebra (ns-3-dce-quagga-umip) and
try to simulate failure in OSPF networks.
I used the quagga-rockfuel example and try to simulate link failure by
using the ipv4::SetDown function but the simulation failed with a
SIGSEGV signal.
My question is then, is link failure possible with your zebra and
ns3 ?, have you already tested it ?
if not, is it easily feasible to add link failure support.
I looked into ns3 with quagga since It seems that global routing
objects in ns3 don't support failure detection with hello protocol,
but if 'iam wrong, please tell me.
Regards,
Bruno

could you give me your simulation script? I'll try to
reproduce what you pointed out.
and it is helpful if you also give me stacktrace of gdb with
the core file.

I guess current version of netlink implementation in ns-3
doesn't have link notification to the application. but it's
possible to notify with modification.

Hello Hajime,
I'm newbie with network simulation, but in real, OSPF use keep alive
messages (hello protocol) to manage adjacencies. What I expect, would
be that quagga detect itself that a link is down because of missing
hello messages.
Anyway, following is the backtrace of the execution:

That is true; global routing is mainly designed for static topologies
for cases in which users don't want to bother with any routing
protocols, and it doesn't support failure detection. That is also why
it is not really well suited for wireless, because it decides that every
device attached to the channel is reachable regardless of the
propagation conditions.

Hey
Is there any easy way to implement a Poissons' distribution for vehicular flow? I'm attempting to model vehicular traffic, but then noticed that Poissons' distribution is not implemented in random-variable.h/.cc. Is there any way I could use existing functions in order to implement this? It's also necessary for me to ensure that the random variable that is generated is also of the type RandomVariable and not double.
Thanks in advance.

check the wiki for the exact way of installing it.
i wonder wheather you have the required dependency installed or not

I have install many times for ns-3 packege follow step from
http://www.nsnam.org/wiki/index.php/Installation#Ubuntu.2FDebian ,
and I try to install code ns-3 from http://code.nsnam.org/thehajime/ns-3-dce-quagga-umip/
but the result show
(2). the message will have problem for develop? or not?

This is SIGUSR1, not SEGFAULT: it's used by some code to handle task
switching. Try the gdb command:
"handle SIGUSR1 nostop"
and
"continue"
switching. Try the gdb command:
"handle SIGUSR1 nostop"
and
"continue"
