That's a problem. As far as the routers are concerned, GRE tunnels are -always- up (unless maybe you turn on GRE keyalives.)

Please have a look at Vincent C. Jones' web site for information on the sorts of things you have to do in order to have tunnel state track interface or connection state.

According to what I've read (and experienced a bit myself), it is fairly common for ADSL links to go down "one hop away", leaving the local interface physically up and able to send packets but the packets are not getting anywhere useful. This requires that you use an end-to-end checking strategy rather than relying on the router detecting a hardware link down.

I am running a pix 515 with ver 6.3 and I need to create a few static routes. I searched and found the command:

ip route 172.16.0.0 255.255.255.0 192.168.150.1

but I get an "invalid keyword route". I am routing internal traffic to a VPN router for three specific IP addresses. I need to add routes for those IP's. What is the command in 6.3 to add a static route?

Thanks,

"ip route" is IOS (or possibly PIX 7). For PIX 6,

route inside 172.16.0.0 255.255.255.0 192.168.150.1

for asa/pix with v7.x it would be also route inside 172.16.0.0 255.255.255.0 192.168.150.1
