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??
You can run the PIX outside interfaces and the router's HSRP group off the same subnet.
The PIX will default to the router's HSRP VIP.
The primary router will be the HSRP primary and you will track the WAN interface. If the WAN link goes down, the HSRP secondary will become the primary, and the PIX will still be pointing to the right address, which is the HSRP VIP.
This is one way to do it...
Configuring HSRP on the LAN interfaces of your Internet routers has nothing to do with who provides your WAN links.
