One of the issues here might be which route is better than the other for a
particular destination.
There is only one gateway of last resort in the routing table, although
there may be more than one candidate default.
If this router is on a stub network, then it might be better to do:
ip route 0.0.0.0 0.0.0.0 interface 1
ip route 0.0.0.0 0.0.0.0 interface 2 10
By changing the admin distance you get a redundant default. If interfface 1
goes down, interface 2 will take over immediately.
If the configuration remains as you have written it, I suspect that you will
have per destination load balancing.
But since routing detail is lost when using static default routes, packets
will not necessarily take the best route to a given destination.
There are other issues, but they depend on the topology and the routing
protocols in use.

Subject: default routes
All:
I know it is possible to place more than one default route in a router.
What are some basic general issues with doing this, considering, that
no routing loops are present.
I am speaking of say:
router 1# ip route 0.0.0.0 0.0.0.0 <interface 1> ... going to network 1
router 1# ip route 0.0.0.0 0.0.0.0 <interface 2> ... going to network 2
In the case of packets being forwarded to this router 1 would the routes
that
are not directly connect be sent out both interfaces?
Thanks in advance.
