NDN路由--OSPFN安装与配置
现在的IP网络的问题已经暴露的很多了，各种改进的网络架构与设想非常多，但其中以基于内容为中心的网络发展最为迅速，其中，NDN的架构最为完整，代码也比较成熟。OSPFN是基于CCNX的，所以之前要安装CCNX，简单的./configure make make install 就可以安装完成，自带很多例子可以跑跑。接下来安装OSPFN，由于还要配置，所以把过程记录在下面。
1.OSPFN安装
最开始需要安装一些必备软件：
sudo apt-get install flex
sudo apt-get install bison
sudo apt-get install m4
sudo apt-get install libssl-dev
sudo apt-get install libexpat-dev
sudo apt-get install libpcap-dev
sudo apt-get install ant
sudo apt-get install openjdk-7-jdk
sudo apt-get install gawk
sudo apt-get install dia
sudo apt-get install texinfo
首先新建一个用户，并在/usr/local/etc下建两个目录：
$ sudo useradd quagga
$ cd /usr/local/etc/
$ sudo mkdir quagga
$ sudo chown quagga:quagga quagga
$ sudo chmod 775 quagga
$ sudo mkdir quagga-state
$ sudo chown quagga:quagga quagga-state
$ sudo chmod 775 quagga-state之后，运行./configure，这里要注意，ubuntu12.04下，/var/run路径每次重启里面新建的quagga-state文件夹会消失，费了好长时间才发现这个问题，修改的./configure如下：
./configure --enable-opaque-lsa --disable-ipv6 --disable-ripd --disable-ripngd --disable-ospf6d --disable-bgpd --disable-bgp-announce --sysconfdir=/usr/local/etc/quagga --localstatedir=/usr/local/etc/quagga-state然后，执行make 和install：
make
make install至此，OSPFN安装完毕。
2.OSPFN配置
首先要得到GRE隧道的IP，由于没有加入到他们的testbed中，所以自己设置一个就好了。
Public IP: 141.225.11.150 Public IP:150.135.82.77
________________________ 10.0.1.10 10.0.1.9 ___________________
|netlogic.cs.memphis.edu |___________________|hobo.cs.arizona.edu|
------------------------ -------------------上图是官网配的图，NDN testbed使用的是10.x.x.x的私有IP地址，因为没有加入进去，所以就还使用它们就好了。Public IP就是本机的IP，由于本地路由器，IP也是10.x.x.x的。。。但还是可以区分出来的~
sudo modprobe ip_gre之后，在/etc/network/interfaces文件中添加如下：
auto lo
iface lo inet loopback
auto netlogic
iface netlogic inet static
address 10.0.1.9
netmask 255.255.255.0
broadcast 10.0.1.255
up ifconfig netlogic multicast
pre-up iptunnel add netlogic mode gre local 10.0.0.104 remote 10.0.0.108 ttl 255
pointopoint 10.0.1.10
post-down iptunnel del netlogic这里，本机IP是10.0.0.104，另一台机子IP是10.0.0.108，相应的两个隧道IP是10.0.1.9和10.0.1.10。现在ifconfig一下：
lo Link encap:本地环回
inet 地址:127.0.0.1 掩码:255.0.0.0
inet6 地址: ::1/128 Scope:Host

发现有了netlogic。然后配置ospfd.conf文件。内容如下：
hostname netlogic_kl
password pwd
enable password pwd
log file /var/log/quagga/ospfd.log
!
!
!
interface netlogic
description link to netlogic_zero
!
access-list ospfn permit 10.0.0.0/8
access-list ospfn deny any
!
router ospf
ospf router-id 10.0.0.104
redistribute connected
distribute-list ospfn out connected
network 10.0.1.8/30 area 0.0.0.0
capability opaque
!
line vty
!
!end of configuration file hereog stdout这个基本上就是官方文档的例子，只是把IP给改成相应的IP。
最后就是最关键的ospfn.conf文件。这个官网的说明文档中没有详细说明，我就把它放在/usr/local/etc/quagga目录下，经测试完全可用。目前OSPFN支持两个命令：ccnname和logdir。说明如下：
1. ccnname name_prefix op_id
name_prefix : a name prefix, in URI format, to be advertised by this router.
op_id : the desired ID for this name LSA. The op_id must be unique among
the name prefixes advertised by the same router.
2. logdir dir
dir : directory to write log files to我的ospfn.conf内容如下：
ccnname /ndn/ustc.edu/1318/ 1
ccnname /ndn/ustc.edu/1316/ 2
logdir /usr/local/etc/最后，开启应用：
$ sudo zebra -d
$ sudo ospfd -d -a
$ ccndstart
$ ospfn截图如下：
在/usr/local/etc里生成了log，log内容如下：
