Dual ISPs with 2 PAN Firewalls

Not applicable

I am in need to set up a branch office with Dual ISPs and PAN firewalls.  Everything I've seen & read detail the process with a single PAN and PBF's.   Has anyone accomplished the same with 2 PANs??  I am trying to get the set up in my head & having issues obviously.    Regards, Dan


ECMP is available from most manufacturers nowadays.

The core switches in this case... are they perhaps L3-switches? 🙂

yes it's a 4506

If you have updated IOS and fairly new supervisor it should support ECMP according to:

Release Notes for Catayst 4500 Series Switch, Cisco IOS XE 3.1.x SG - Cisco Systems


8-Way CEF Load Balancing Yes Yes Yes



Might I be able to get away with an active/passive employing IP SLA on the core 4506 ?  Relatively confident we will not need or achieve 40Gb throughput.. Bear in mind, this is all new to me.
