FWSM Connection to ISP Network

[gdrandles]

Our ISP has two routers onsite.  The primary router has a 40MB connection to the Internet and the secondary router as a 20MB connection to the Internet.  I am configuring our two 6509's with a FWSM in each so that the MSFC is inside and the FW is facing the ISP routers.

Question: Can I setup HSRP between the FW and the ISP routers?

I have attached a diagram showing the connection between the ISP and the 6509.

Thanks

Hello,

HSRP is a redundancy mechanism between two routers.  HSRP cannot be configured between a router and the FWSM.

The FWSM can be configured with failover for redundancy purposes.

Hope this helps.

Allen,

  I have updated the drawing to show the change between the FW and the IPS routers.  If we are unable to do HSRP at the FW level, then I will have to contact the ISP and have them change the /29 to a /30 and assign the IP's accordingly.  We own the entire /28 range.  Once they make the change then there would be two seperate paths in and two seperate paths out.  Wouldn't this be a problem possibly causing routing loops?
