VRRP封包格式<br /> <br /> VRRP 中來源 MAC 位址格式必須為 00-00-5E-00-01-XX<br /> 其中 XX 為虛擬路由器的編號(Virtual Router Identifier，簡寫為VRID)<br /> <br /> 目的 IP 位址必須是群播位址 240.0.0.18<br /> TTL 則必須設定為 255 ，否則會被丟棄<br /> IP 的上一層是 VRRP ，故 Protocol 欄位數值是 112 (0x70 in 16進位)<br /> <br /> 2. VRRP基本原理<br /> <br /> 網路上有許多路由器（Router）<br /> 跑著不同的路由協定（Routing Protocol）<br /> 其中跑著 VRRP 的 router 我們稱為 VRRP router<br /> 而一個虛擬路由器（Virtual Router）可以說是一群 VRRP router 的組合<br /> 因為實際運作的路由器是這些路由器中的 master，所以才說這一群是「一個」虛擬路由器<br /> 此外， virtual router 有一個辨識號碼（VRID）和一組相關聯的 IP 位址<br /> 因此可以說同一個 virtual router 底下的 VRRP router 都具有相同的 VRID，稱它們為同一 group<br /> <br /> 那 VRRP 是幹什麼的呢？<br /> 剛說 virtual router 底下有很多 VRRP router<br /> VRRP 就是在選其中一個 router 作為 master<br /> 剩餘的則成為 backup<br /> 若是 master 掛掉了，則從 backup 中依優先權再選出一個 master<br /> 其實可以再進一步看<br /> VRRP 封包格式中有一欄位叫做 Adver Int（Advertisement Interval）<br /> 預設為一秒，此欄是用來判斷是否該有 backup 起來作為 master 的判斷因素之一<br /> <br /> 3. 最後做個小結<br /> <br /> VRRP 是用在 static default routed environment（靜態預設路由環境）<br /> 其功用在於避免 single point of failure（單點故障）<br /> 最大優點是可以不用在每個 end-host 作 dynamic routing 或 router discovery protocol 的組態設定<br /> 而有高可得性的預設路徑（high availability default path）<br /> <br /> For Router R1:<br /> /interface vrrp add interface=ether1 vrid=49 priority=150<br /> /ip address add address=192.168.1.1/24 interface=ether1<br /> /ip address add address=192.168.1.254/32 interface=vrrp1<br /> <br /> For Router R2:<br /> /interface vrrp add interface=ether1 vrid=49 priority=100<br /> /ip address add address=192.168.1.2/24 interface=ether1<br /> /ip address add address=192.168.1.254/32 interface=vrrp1</div>
