8.1 VRRP configuration
VRRP (Virtual Router Redundancy Protocol) is a network protocol designed for increased availability of routers,
acting as a default gateway. This is performed by aggregation of a router group into a single virtual router and
assigning a shared IP address, that will be used as a default gateway for computers in the network.
8.1.1 Configuration algorithm
Step
Description
Command
Keys
1
Switch to the interface/tunnel/
network bridge configuration mode
for which it is necessary to configure
VRRP
esr(config)#
interface <IF-
TYPE><IF-NUM>
<IF-TYPE> – interface type;
<IF-NUM> – F/S/P – F frame (1), S –
slot (0), P – port.
esr(config)# tunnel
<TUN-TYPE><TUN-NUM>
<TUN-TYPE> – tunnel type;
<TUN-NUM> – tunnel number.
esr(config)# bridge
<BR-NUM>
<BR-NUM> – bridge number.
2
Configure the required parameters on the interface/tunnel/network bridge including IP address
3
Enable VRRP process on IP interface.
esr(config-if-gi)#
vrrp
esr(config-if-gi)#
ipv6 vrrp
4
Set virtual IP address of VRRP router.
esr(config-if-gi)#
vrrp ip <ADDR/LEN>
<ADDR/LEN> – virtual IP address,
defined as AAA.BBB.CCC.DDD/EE
where each part AAA-DDD takes
values of [0..255] and EE takes values
of [1..32]. You can specify several IP
addresses separated by commas. Up
to 4 IP addresses can be assigned to
the interface.
