[c-nsp] PIX VPN Mesh w/ OSPF

[Dave Breiland]

I want to make sure I'm on the right track and haven't set myself up for 
failure...
I have 4 offices around the US.  Each site has a different ISP... 
connected with a T1.  My plan was to have a PIX-515 at each site.  I 
would use the PIX's to create VPNs between each and every site.  My 
guess is that there will be times that the ISPs will have routing issues 
between each other.  To get around this, I would think that...
-Route between Site A and Site B fails
-Site B re-routes data to Site C which still has VPN to Site A.
Presumably this would require EIGRP or OSPF.  Unfortunately it looks 
like the PIX only supports OSPF. 
Is this the right direction/steps I should be taking?
Am I just over complicating things?
Has anyone had success with OSPF and the PIXs?

Thanks for any input.
