our customer have 2 cisco routers 2811 for internet and 2 ASA firewalls . Also the customer has 2M leased line from the ISP for internet . our customer will get another internet line from the same ISP to be used as a backup for the main line.
if i want to configure HSRP between the two internet routers and configuring the firewalls for failover , does that need to use 5 real ip addresses on the routers and firewalls interfaces or not???
Another guestion :
if the backup line is obtained from different ISP , can i configure HSRP on the routers??
