They finally did it, but only supported on Next Gen ASAs!  [cid:image001.png at 01CF6928.F3A3CB80] [cid:image002.gif at 01CF6928.F3A3CB80]

So frustrating, I can't believe 9.1 is going to be the last version for the last generation ASA.

Hi

Lots of info.

So  I have OSPF running, actually on top of iBGP. Pity the ASA doesn't handle iBGP :(

So this is for when OSPF is down, I want a static dgw. I have 2 potential DGW, I would like to preference 1 over the other. The other holds all the backup links..

No sure where I got the impression that cisco would invalidate a route if it wasn't arp-able.
