1-5

The configuration in Figure 1-3 shows that IP address 1.1.1.1 provides

connectivity to external networks. If that connection fails and the virtual router 1

on router B continues to forward traffic, you still lose connectivity to external

networks. However, if you designate IP address 1.1.1.1 as the critical IP address

for virtual router 1 on router B, and IP address 1.1.1.1 fails, then virtual router 1

on router A becomes the master virtual router and begins forwarding traffic.
