Issue with NS2.34 with BGP patch
 

Hello Everyone,

I'd like to use NS2 version 2.34 using the BGP patch (available at : http://www.ensc.sfu.ca/~ljilja/cnl/p...-2.34-BGP.html)

I've followed the procedure but when I try to run './install' from the ns-allinone-2.34 directory I got :

(...)

See http://www.isi.edu/nsnam/ns/ns-problems.html for problems


I've replaced #include<string.h> with #include<cstring> in the 'ipaddress.cc' but it does not work...
I work with Ubuntu10.4...
Can you help me ?

Thanks !

Welcome to LQ.

Ubuntu 10.04 Lucid :

Probably :
sudo apt-get install g++-4.3

cd ns-allinone-2.34/ && export CC=gcc-4.3 CXX=g++-4.3 && ./install
1) You may have to run 'make clean' in ns-allinone-2.34/ns-2.34/.
2) May be an even older compiler is required.
The g++-3.4 from Ubuntu 8.04 Hardy can be used.
..

Thanks knudfl it's working now ! The problem was the compiler.
Now I have written a script to use BGP

I would like to emulate a network made up of 2 AS; and in each AS 5 nodes.
For that I have installed the NS-2 2.34 version with the BGP patch.
I created two BGP nodes like this :

$ns node-config -BGP ON
set n0 [$ns node 0:10.0.0.1]
set n1 [$ns node 1:10.1.1.1]
$ns node -config -BGP OFF

And I would like to create the other nodes using the dynamic routing (LS or DV)

I know that I cannot use the line : $ns rtproto DV (or LS) otherwise I will be contradictory with the begin with BGP...

Do you have an advice on that issue? Is there a possibility to put locally the dynamic routing for a node or a link ?

hello, which commands have you used to solve the BGP patch issues. thanks

# 4, @ lovsis
There are not supposed to be any issues with BGP.
Which OS are you using ? Name and version, please.

Examples : 1) Ubuntu 10.04, 10.10
cd ns-allinone-2.34/ && tar xvf ns-2.34-bgp_2.0.tgz &&
patch -p0 < ns-2.34-bgp_2.0_patch && export CC=gcc-4.1 CXX=g++-4.1 && ./install

2) Ubuntu 11.04 : The "export command" is : export CC=gcc41 CXX=g++41
3) Fedora : export CC=gcc34 CXX=g++34

Simulation example : ns-allinone-2.34/ns-2.34/tcl/bgp/test/
ns drop-peer2.tcl : OK.

.

I am using ubuntu 12.04,i tried to install ns-2.34 but i am getting this error while installing..

I want information regarding bgp only but i am not able to install ns-2.34..i have installed gcc-4.4


but i am getting this error

# 8

No ns2 any version can be installed until you do $ sudo apt-get install libxmu-dev

Did you read post # 7 : sudo apt-get install \
g++ g++-4.4 make automake autoconf libtool patch build-essential xgraph libxmu-dev


And post # 5 :

@knudfl




yashwanth@ubuntu:~$ cd ns-allinone-2.34/ && tar xvf ns-2.34-bgp_2.0.tgz && patch -p0 < ns-2.34-bgp_2.0_patch && export CC=gcc41 CXX=g++-4.1 && ./install
while doing this i am getting this

patching file ns-2.34/common/node.cc
Reversed (or previously applied) patch detected! Assume -R? [n]


next what shall i do..

# 10
Happens when you apply the patch more than one time, usually.
You can just hit <Enter> for every "Assume -R? [n] "

Thanks for helping me

while installing ns-2.34 i am getting this

previously i changed the

CC= @CC@
and change it to:
CC= gcc-4.4 in .bashrc



but now these lines are not there in .bashrc itself

# 13
Please don't do that. Makes no sense. Use the appropriate export command :
export CC=gcc41 CXX=g++41


# 12
If sudo was used for any commands, you will have no access : Permission denied.
Delete everything, and do :

sir,i followed all the steps above you provided..and installed ns2.34 in uduntu 12.04,while validating i got this
