In te1/0/2 interface configuration mode, enable WAN mode and exit:
еsr(config-if)# wan load-balance enable
еsr(config-if)# exit
To switch into redundancy mode, configure the following:
Proceed to WAN rule configuration mode:
еsr(config)# wan load-balance rule 1
MultiWAN function may also work in redundancy mode when traffic is directed to the active interface with the
highest weight. To enable this mode, use the following command:
еsr(config-wan-rule)# failover
11.10 IS-IS configuration
IS-IS — ISO standardized dynamic routing protocol based on link-state. It provides fast convergence and
excellent scalability, makes economical use of network bandwidth, and uses the Dijkstra Algorithm to calculate
the best routes. A distinctive feature of the IS-IS protocol is to work on top of the data link layer of the OSI
model, so it is not bound to a specific network layer protocol.
11.10.1 Configuration algorithm
Step Description Command Keys
1 Create an IS-IS process and
switch to the parameters
configuration mode of this
process.
esr(config)# router isis <ID>
[vrf <VRF>]
<ID> – process number, takes values of
[1..65535];
<VRF> – VRF instance name, set by the
string of up to 31 characters.
2 Set NET address. esr(config-isis)#net {<NET>} <NET> – NET address, format:
ff[.ffff.ffff.ffff.ffff.ffff.ffff].ffff.ffff.ffff.00.
3 Enable IS-IS process. esr(config-isis)# enable
4 Set the authentication
algorithm for the L2 layer
(optional).
esr(config-isis)#
authentication domain
algorithm <ALGORITHM>
<ALGORITHM> – authentication algorithm:
cleartext – unencrypted password;
md5 – password is hashed by md5
algorithm. 
5 Set the authentication
password for the L2 layer
(optional).
esr(config-isis)#
authentication domain key
ascii-text { <CLEAR-TEXT> |
encrypted <ENCRYPTED-
TEXT> } 
<CLEAR-TEXT> – password, set by the
string of 8 characters;
<ENCRYPTED-TEXT> – encrypted
password of 8 bytes (16 characters) in
hexadecimal format (0xYYYY...) or
(YYYY...).
