5.8 MultiWAN configuration
MultiWAN technology establishes a fail-safe connection with redundancy of links from multiple providers and
solves the problem involving traffic balancing between redundant links.
5.8.1 Configuration algorithm
Step
Description
Command
Keys
1
Configure interfaces through which
MultiWAN will operate: set ip
addresses and specify security zone.
2
Write static routes through WAN (if
required).
esr(config)# ip route
<SUBNET> wan load-
balance rule <ID>
[<METRIC>]
<ID> – identifier of the rule being
created (see item 2).
<METRIC> – route metric, takes values
of [0..255].
3
Create WAN rule and switch to the
rule parameters configuration mode.
esr(config)# wan
load-balance rule
<ID>
<ID> – identifier of the rule being
created, takes values in the range of
[1..50].
4
Specify interfaces or tunnels which
are gateways in the route created by
MultiWAN service.
esr(config-wan-rule)#
outbound
{ interface <IF> |
tunnel <TUN> }
[WEIGHT]
<IF>– interface name;
<TUN> – tunnel name;
[WEIGHT] – tunnel or interface weight,
defined in the range of [1..255]. If the
value is equal 2, than 2 times more
traffic will be transmit via the given
interface than via the interface with the
default value. A route with the highest
weight will be active in the redundancy
mode. Default value: 1
5
Describe the rules (optionally).
esr(config-wan-rule)#
description
<DESCRIPTION>
<DESCRIPTION> – wan rule
description, set by the string of up to
255 characters.
6
You can use this command to switch
from the balancing mode to the
redundancy mode.
esr(config-wan-rule)#
failover
7
Enable wan rule.
esr(config-wan-rule)#
enable
8
Create a list of IP addresses to
check the connection integrity and
perform the switching to the list
parameters configuration mode.
esr(config)# wan
load-balance target-
list <NAME>
<NAME> – list name, set by the string
of up to 31 characters.
