Network requirements
• I n t h e s e g m e n t 2 0 2. 3 8 .16 0 . 0 / 24 , s o m e h o s t s u s e 2 02. 3 8 .16 0 .111/24 as their default gateway and
some hosts use 202.38.160.112/24 as their default gateway.
• Load sharing and mutual backup between default gateways can be implemented by using VRRP
groups.
