We have two core 6509 switchs running HSRP.

We have two firewalls in active/standby roles and want to implement a high availablility structure with the core switches, firewalls and edge router.

In order to do this, I believe the inside interface of each firewall should go to each core switch, then have a seperate DMZ switch for each firewall, with redundant connections from the servers to each DMZ.

My question involves the Internet edge router and MPLS router.

Is there any way to have the Internet edge router have dual connection to the firewalls, and MPLS router?

How is this normally done?
