4.14.3 Example for Configuring the Multi-Instance VRRP

In this example, by configuring different default gateway addresses for CEs on different VPNs,
you can implement load balancing of a VRRP backup group and communication between hosts
of the same VPN.

Figure 4-7, there are two VPN networks: VPN RED and VPN BLUE. Configure
Networking Requirements
l PE-A and PE-B are configured as VRRP backup group 1 and VRRP
backup group 2. In backup group 1, PE-A serves as the master device
and PE-B serves as the backup device. In backup group 2, PE-A
serves as the backup group and PE-B serves as the master device.
l CE-A uses the virtual IP address of VRRP backup group 1 as its
default gateway.
l CE-B uses the virtual IP address of VRRP backup group 2 as its
default gateway.
l CE-A and CE-D belong to the VPN-BLUE instances.
l CE-B and CE-C belong to the VPN-RED instances.
