following command to enable ICMP Echo Response:

Symmetrical Configuration
Figure 9 shows a VRRP configuration with two routers and two virtual routers. Routers R1 and R2
are both configured with two virtual routers (
VRID=1 and VRID=2).
Note: Do not use an IP address for VRRP that is already configured for load-balancing.
Router R1 serves as:
• Master for
VRID=1
• Backup for VRID=2
Router R2 serves as:
• Master for
VRID=2
• Backup for VRID=1
This configuration allows you to load-balance traffic coming from the hosts on the 10.0.0.0/16
subnet and provides a redundant path to either virtual router.
Note: This is the recommended configuration on a network using VRRP.
