環境：三臺redhat6.5（VM虛擬機）
一、ospf協議
OSPF(Open Shortest Path First開放式最短路徑優先）是一個內部網關協議(Interior Gateway Protocol，簡稱IGP），用於在單一自治系統（autonomous system,AS）內決策路由。是對鏈路狀態路由協議的一種實現，隸屬內部網關協議（IGP），故運作於自治系統內部。
PS：這裏不過多講解ospf協議，可在網上自行查找學習
二、配置
首先下載安裝軟件包，其他yum源以及網絡配置就不再介紹了，三臺配置也是一樣的
下載地址：http://download.openpkg.org/components/cache/quagga/
本人這裏使用的版本是quagga-0.99.17.tar.gz
相關依賴包：gcc readline readline-devel
#tar zxf quagga-0.99.17.tar.gz #yum install -y gcc readline readline-devel #cd quagga-0.99.17 #進入目錄進行源碼編譯安裝 #./configure --enable-vtysh--enable-user=root --enable-group=root --enable-vty-group=root # make && make install
修改配置文件:
在/etc/services文件裏面添加以下內容：
# vim /etc/services zebrasrv 2600/tcp # zebra service zebra 2601/tcp # zebra vty ripd 2602/tcp # RIPd vty ripngd 2603/tcp # RIPngd vty ospfd 2604/tcp # OSPFd vty bgpd 2605/tcp # BGPd vty ospf6d 2606/tcp # OSPF6d vty ospfapi 2607/tcp # ospfapi isid 2608/tcp # ISISd vty
修改quagga的配置文件：
# mkdir /usr/local/etc/sample # mv /usr/local/etc/*.sample/usr/local/etc/sample/ # mv /usr/local/etc/bgpd.conf.sample2/usr/local/etc/sample/ # cp /usr/local/etc/sample/bgpd.conf.sample/usr/local/etc/bgpd.conf # cp/usr/local/etc/sample/ospfd.conf.sample /usr/local/etc/ospfd.conf # cp/usr/local/etc/sample/ospf6d.conf.sample /usr/local/etc/ospf6d.conf # cp /usr/local/etc/sample/ripd.conf.sample/usr/local/etc/ripd.conf # cp /usr/local/etc/sample/vtysh.conf.sample/usr/local/etc/vtysh.conf # cp/usr/local/etc/sample/ripngd.conf.sample /usr/local/etc/ripngd.conf # cp/usr/local/etc/sample/zebra.conf.sample /usr/local/etc/zebra.conf
修改ospfd的配置文件：
# vim /usr/local/etc/ospfd.conf ! -*- ospf -*- ! ! OSPFd sample configuration file ! ! hostname ospfd password zebra enable password please-set-at-here router ospf network 10.235.117.0/24 area 0 #將網段宣告進ospf中 log stdout
三、啓動驗證
接下來啓動即可：
# /usr/local/sbin/ospfd -d # /usr/local/sbin/zebra -d # vtysh Hello, this is Quagga (version 0.99.17). Copyright 1996-2005 Kunihiro Ishiguro, etal. test.xiaomi.com# show running-config Building configuration... Current configuration: hostname Router hostname ospfd log stdout password zebra enable password zebra enable password please-set-at-here interface eth0 ipv6nd suppress-ra interface lo router ospf network 10.235.117.0/24 area 0.0.0.0 line vty end test.xiaomi.com# show ip ospf database OSPF Router with ID (10.235.117.22) Router Link States (Area0.0.0.0) Link ID ADV Router Age Seq# CkSum Link count 10.235.117.22 10.235.117.22 3 0x80000003 0x0735 1 10.235.117.27 10.235.117.27 9 0x80000005 0xf832 1 10.235.117.28 10.235.117.28 10 0x80000005 0xf631 1 Net Link States (Area0.0.0.0) Link ID ADV Router Age Seq# CkSum 10.235.117.28 10.235.117.28 10 0x80000003 0xe5cf
vtysh是quagga進入模擬路由的，進去可以像正常路由器上面命令一樣去查看信息。
我這裏是啓動了三臺ospfd進程，配置都是一樣的，重複上面步驟即可，趕緊get起來吧！！！
