Configuration Roadmap
The configuration roadmap is as follows:
1. Assign an IP address to each interface of each Router and configure OSPF on each
Router to ensure network connectivity.
2. Configure a VRRP IPv6 backup group on routers and set different VRRP priorities for the
devices to determine the master or backup state for the routers, which ensures device-level
reliability for network links.
Data Preparation
To complete the configuration, you need the following data:
l IP address of each interface on each device (For details, see configuration files.)
l VRRP priority of each router in the VRRP IPv6 backup group
l VRID (1) and virtual IPv6 address (2001:db8::100) for the VRRP IPv6 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 hosts. For configuration details, see the configuration file of this example.
Set the IPv6 address of a default gateway for host A to 2001:db8::100 and that for host B to
2001:db8:3::2.
