Description
Command
Keys
prohibit
– when specifying the
command, the packets to this
subnet will be removed by the
device, a sender will receive in
response ICMP Destination
unreachable (Communication
administratively prohibited, code
13);
<METRIC> – route metric, takes values
of [0..255];
<TRACK-ID> – Tracking object
identifier. If the router is bound to the
Tracking object, it will appear in the
system only after meeting all
requirements specified in the object.
6
Configure IP address, the
availability of which is checked by
sending pings. It is necessary to
allow ICMP on the Firewall.
esr(config-bridge)#
vrrp track-ip
<AAA.BBB.CCC.DDD>
AAA.BBB.CCC.DDD – host IP address,
where each part takes values of
[0..255].
7
The interval at which pings are
sent.
esr(config-bridge)#
vrrp track-ip
<seconds>
<seconds> – time interval in seconds
[3..60]. Default
value is 10.
8
The number of pings that are sent
when monitoring a remote
address.
esr(config-bridge)#
vrrp track-ip packets
<packets>
<packets> – number of packets to be
sent [1..5]. Default value: 5
8.2.2 Configuration example
Objective:
Virtual gateway 192.168.0.1/24 is organized for 192.168.0.0/24 subnet, using VRRP protocol and routers R1
and R2. There is a link with a singular subnet 192.168.1.0/30 between R1 and R2 routers. Subnet 10.0.1.0/24 is
terminated only on R2 router. PC has IP address - 192.168.0.4/24 and default gateway 192.168.1.1.
When router R1 is in vrrp backup state, traffic from PC will be transmitted without any additional settings.
When router R1 is in vrrp master state, additional route is necessary for subnet 10.0.1.0/24 through interface
192.168.1.2.
