RouteOs可以做双机冗余吗

RouteOs可以做双机冗余吗？可以提高路由的稳定性。

bow

可以用vrrp作双机热备.当备用机找不到主机是就会接管过来.但外网链路故障时.备机还可以找到主机.就不起作用了.所以是一种设备备份的方式

可以从一定程度上降低故障率和提高网络稳定性。BOW：  vrrp是什么呢？哪里有它的资料可以查阅？

搜索就行

Virtual Router Redundancy Protocol虚拟路由冗余协议RouterOS就支持

  应该怎么做呢？谈谈你的经验~！

Configuring Master VRRP routerFirst of all we should create a VRRP instance on this router. We will use the priority of 255 for thisrouter as it should be preferred router.[admin@MikroTik] ip vrrp> add interface=local priority=255[admin@MikroTik] ip vrrp> printFlags: X - disabled, I - invalid, M - master, B - backup0 M name="vr1" interface=local vrid=1 priority=255 interval=1preemption-mode=yes authentication=none password="" on-backup=""on-master=""[admin@MikroTik] ip vrrp>Next the virtual IP address should be added to this VRRP instance[admin@MikroTik] ip vrrp> address add address=192.168.1.1/24 \\... virtual-router=vr1[admin@MikroTik] ip vrrp> address printFlags: X - disabled, A - active# ADDRESS NETWORK BROADCAST VIRTUAL-ROUTER0 192.168.1.1/24 192.168.1.0 192.168.1.255 vr1[admin@MikroTik] ip vrrp>Now this address should appear in /ip address list:[admin@MikroTik] ip address> printFlags: X - disabled, I - invalid, D - dynamic# ADDRESS NETWORK BROADCAST INTERFACE0 10.0.0.1/24 10.0.0.0 10.0.0.255 public1 192.168.1.2/24 192.168.1.0 192.168.1.255 local2 D 192.168.1.1/24 192.168.1.0 192.168.1.255 local[admin@MikroTik] ip address>Configuring Backup VRRP routerNow we will create VRRP instance with lower priority (we can use the default value of 100), so thisrouter will back up the preferred one:[admin@MikroTik] ip vrrp> add interface=local[admin@MikroTik] ip vrrp> printFlags: X - disabled, I - invalid, M - master, B - backup0 B name="vr1" interface=local vrid=1 priority=100 interval=1preemption-mode=yes authentication=none password="" on-backup=""on-master=""[admin@MikroTik] ip vrrp>Now we should add the same virtual address as was added to the master node:Page 283 of 564[admin@MikroTik] ip vrrp> address add address=192.168.1.1/24 \\... virtual-router=vr1[admin@MikroTik] ip vrrp> address printFlags: X - disabled, A - active# ADDRESS NETWORK BROADCAST VIRTUAL-ROUTER0 192.168.1.1/24 192.168.1.0 192.168.1.255 vr1[admin@MikroTik] ip vrrp>Note that this address will not appear in /ip address list:[admin@MikroTik] ip address> printFlags: X - disabled, I - invalid, D - dynamic# ADDRESS NETWORK BROADCAST INTERFACE0 10.1.0.1/24 10.0.0.0 10.0.0.255 public1 192.168.1.3/24 192.168.1.0 192.168.1.255 local[admin@MikroTik] ip address>Testing fail overNow, when we will disconnect the master router, the backup one will switch to the master state:[admin@MikroTik] ip vrrp> printFlags: X - disabled, I - invalid, M - master, B - backup0 M name="vr1" interface=local vrid=1 priority=100 interval=1preemption-mode=yes authentication=none password="" on-backup=""on-master=""[admin@MikroTik] ip vrrp> /ip address printFlags: X - disabled, I - invalid, D - dynamic# ADDRESS NETWORK BROADCAST INTERFACE0 10.1.0.1/24 10.0.0.0 10.0.0.255 public1 192.168.1.3/24 192.168.1.0 192.168.1.255 local2 D 192.168.1.1/24 192.168.1.0 192.168.1.255 local[admin@MikroTik] ip vrrp>

可以让两台机器互为热备，会更完美vrrp比cisco的hsrp真是好多了

ricky

mikrotik的举例中是双线路备份的例子，好像不是双机备份的例子。

bow

是双机热备

nihaoya

准确地说，应该是双线双机热备。一个外网是10.0.0.1，另一个外网是10.1.0.1。问题是能否单外网双机热备？希望有高手来解答！！！

  当然可以啊两个路由器虚拟出一个网关给用户使用，一个做master，一个做slave，master断了slave就会接替，但虚拟网关不变也就是说用户几乎不受影响

这个到是不错
