The virtual IP addresses should be the same for each node of a virtual router. Example To add a virtual address of 192.168.1.1/24 to the vr1 VRRP router: [admin@MikroTik] ip vrrp> address add address=192.168.1.1/24 \ \... virtual-router=vr1 [admin@MikroTik] ip vrrp> address print Flags: X - disabled, A - active # ADDRESS NETWORK BROADCAST VIRUAL-ROUTER 0 192.168.1.1/24 192.168.1.0 192.168.1.255 vr1 [admin@MikroTik] ip vrrp> A simple example of VRRP fail over Description VRRP protocol may be used to make a redundant Internet connection with seamless fail-over. Let us assume that we have 192.168.1.0/24 network and we need to provide highly available Internet connection for it. This network should be NATted (to make fail-over with public IPs, use such dynamic routing protocols as BGP or OSPF together with VRRP). We have connections to two different Internet Service Providers (ISPs), and one of them is preferred (for example, it is cheaper or faster). Page 282 of 568 Copyright 1999-2005, MikroTik.

This example shows how to configure VRRP on the two routers shown on the diagram. The routers must have initial configuration: interfaces are enabled, each interface have appropriate IP address (note that each of the two interfaces should have an IP address), routing table is set correctly (it should have at least a default route). SRC-NAT or masquerading should also be configured before. See the respective manual chapters on how to make this configuration. We will assume that the interface the 192.168.1.0/24 network is connected to is named local on both VRRP routers Configuring Master VRRP router First of all we should create a VRRP instance on this router. We will use the priority of 255 for this router as it should be preferred router. [admin@MikroTik] ip vrrp> add interface=local priority=255 [admin@MikroTik] ip vrrp> print Flags: X - disabled, I - invalid, M - master, B - backup 0 M name="vr1" interface=local vrid=1 priority=255 interval=1 preemption-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 print Flags: X - disabled, A - active # ADDRESS NETWORK BROADCAST VIRTUAL-ROUTER 0 192.168.1.1/24 192.168.1.0 192.168.1.255 vr1 [admin@MikroTik] ip vrrp> Now this address should appear in /ip address list: [admin@MikroTik] ip address> print Flags: X - disabled, I - invalid, D - dynamic # ADDRESS NETWORK BROADCAST INTERFACE 0 10.0.0.1/24 10.0.0.0 10.0.0.255 public 1 192.168.1.2/24 192.168.1.0 192.168.1.255 local 2 D 192.168.1.1/24 192.168.1.0 192.168.1.255 local [admin@MikroTik] ip address> Configuring Backup VRRP router Now we will create VRRP instance with lower priority (we can use the default value of 100), so this router will back up the preferred one: [admin@MikroTik] ip vrrp> add interface=local [admin@MikroTik] ip vrrp> print Flags: X - disabled, I - invalid, M - master, B - backup 0 B name="vr1" interface=local vrid=1 priority=100 interval=1 preemption-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 568 Copyright 1999-2005, MikroTik.
