router loop0 traffic isn't effected by access-list

I created a route map that states all Loopback0 network traffic should take
a certain Serial interface (Default is use E0).

However, if I traceroute and state the source is loopback0 then I don't
match any packets.

If I recall right, this is because traffic generated from the router won't
be filtered by access-list 1. I should move from a loopback0 to a real
ethernet interface - right ?

interface Loopback0
ip address 172.16.10.1 255.255.255.0
!
interface Ethernet0
ip address 172.19.10.2 255.255.255.0
!
interface Serial0
ip address 172.17.1.2 255.255.255.0
!
access-list 1 permit 172.16.10.0
route-map takeserial0 permit 10
match ip address 1
set interface Serial0
!
END
