You can not do it that way, here is why:
Solution
The solution is to remove the old static routes to the LAN (172.31.10.0) and configure new static routes, this time specifying the interface through which the next hop must be reached. This will allow the floating static route on R1 to get installed when the Serial 3/2 interface is shut.
R1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#no ip route 172.31.10.0 255.255.255.0 10.10.10.2
R1(config)#no ip route 172.31.10.0 255.255.255.0 192.168.20.2 250
R1(config)#ip route 172.31.10.0 255.255.255.0 Serial3/2 10.10.10.2
R1(config)#ip route 172.31.10.0 255.255.255.0 Serial3/3 192.168.20.2 250
R1(config)#end

Hello,
I was wondering about the following:
ip route 0.0.0.0 0.0.0.0 Ethernet0/0 66.102.3.6 250
can you modify to just:
ip route 0.0.0.0 0.0.0.0 Ethernet0/0 250
It appears that you have the next hop to both the interface and the ip
address. I would think you would only need the interface or the ip
address but not both. Please let us know the results.

Subject: Real World: Access List/NAT Issue
After my last posting I got request for more real world issues, so here
is another:
When the serial interface goes down, the ethernet interface comes up but
no one can get to the internet I think beacuse of an error in the access
list or NAT translations.
Thanks in advance
