14.1 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.
14.1.1 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/network bridge, including IP address.
3 Enable VRRP process on IP
interface.
esr(config-if-gi)# vrrp
esr(config-if-gi)# ipv6 vrrp
