Configuration Roadmap
The configuration roadmap is as follows:
l
Assign an IP address to each interface to ensure IP connectivity.
l
Configure a VRRP backup group on routers and set different VRRP priorities for the
devices to determine the master or backup state for the routers. This configuration ensures
device-level reliability for network links.
Data Preparation
To complete the configuration, you need the following data:
l
IP address of each interface (For detailed information, see "Data Preparation" in
.)
l
VLAN ID (10) and mode (untagged) for adding interfaces connecting the switch to
Router A and Router B to the VLAN
l
VRID (1) and virtual IP address (10.1.1.111) for a VRRP backup group configured on
Router A and Router B
l
VRRP priorities (120 for Router A and 100 for Router B)
l
Preemption delay (20s)
Procedure
Step 1
Configure the devices to ensure network connectivity. The configuration details are not provided
here.
# Assign 10.1.1.111 to the default gateway for host A.
