Routing Issue.jpg

Hello
If all traffic defaults via DMPVPN and you want to route certain via the xDSL path then you would require policy-based routing for egress traffic to traverse the xDSL path.
Note: the return traffic may not necessary return via the same path, in this case you will need to either dynamically advertise the path for that specific network to be preferred or append PBR on the destination side.


example:
track timer interface 2

track 10 interface <xdsl> line-protocol
access-list 10 permit 172.16.32.0 0.0.0.255

route-map pbr
match ip address 10
set ip next-hop verify-availability <adsl next hop> 1 track 10

int vlan 1
ip policy-route pbr

Not sure what you mean by destination is changed after some time,can you elaborate?

For the return path - Yes most probably it will need to be, either by PBR or dynamic routing with path engineering so traffic returns the way you want it to.
Can you elaborate on how you network is setup, what routing process (static/dynamic) you use etc...

friend that it case, there is no issue at all, 
GRE (DMVPN) is route-based VPN and the traffic is route via the GRE tunnel and other side learn this prefix via GRE tunnel. 

if you want to make some traffic go other than GRE tunnel you  can not use static route ?? why 
because the static route have AD =1 and direct is 0 and since the GRE for router  is direct connect so it 0 
this make all route via GRE tunnel and never check static route. 
solution 
use PBR instead of static route
