I work with Cisco CSRs. On all of my previous CSRs in AWS, I have the following:

AWS-ENV-CSR-R1#sh run | in ip route
ip route 0.0.0.0 0.0.0.0 Tunnel1
ip route 0.0.0.0 0.0.0.0 Tunnel2 2

AWS-ENV-CSR-R1#sh ip cef 1.2.3.4
0.0.0.0/0
attached to Tunnel1

AWS-ENV-CSR-R1#sh ip route

Gateway of last resort is 0.0.0.0 to network 0.0.0.0

S* 0.0.0.0/0 is directly connected, Tunnel1

However, in my Azure environment, I have the following:

MAZ-ENV-CSR-1-R1#sh run | in ip route
ip route 0.0.0.0 0.0.0.0 Tunnel1
ip route 0.0.0.0 0.0.0.0 Tunnel2 2

MAZ-ENV-CSR-1-R1#sh ip route

Gateway of last resort is not set

MAZ-ENV-CSR-1-R1#sh ip cef 1.2.3.4
0.0.0.0/0
no route

Are there any ideas as to why this shows that the gateway is not set?

Thank you!

If the interface to which your static route points is not up, then the route is withdrawn from the routing table. You can only route to an UP/UP interface.

Apparently, both tunnels to which your static default routes point are down. If you bring up a tunnel, then the route will be placed into the routing table.
