David,
>From the link below:
Note: If you configure multiple networks as candidate default routes
using the ip default-network command, the network that has the lowest
administrative distance is chosen as the network for the gateway of
last resort. If all the networks have the same administrative distance
then the network listed first in the routing table (show ip route
lists the routing table) is chosen as the network for the gateway of
last resort. If you use both the ip default-network and ip route
0.0.0.0 0.0.0.0 commands to configure candidate default networks, and
the network used by the ip default-network command is known
statically, the network defined with the ip default-network command
takes precedence and is chosen for the gateway of last resort.
Otherwise if the network used by the ip default-network command is
derived by a routing protocol, the ip route 0.0.0.0 0.0.0.0 command,
which will have a lower administrative distance, takes precedence and
is chosen for the gateway of last resort. Lastly, if you use multiple
ip route 0.0.0.0 0.0.0.0 commands to configure a default route,
traffic is load-balanced over the multiple routes.

Subject: Two Default Routes which path?
If I have say a 25xx router or any router with two serial interfaces,
and I
put a default route say
ip route 0.0.0.0 0.0.0.0 serial 0
ip route 0.0.0.0 0.0.0.0 serial 1
What will happen to the packets if there is no route in the table?
Will
they all go down the first default route? Will the packets alternate
based
on sessions?
Amazing how many smart people with lots of experience I have asked
that do
not know the answer to this question including myself!
Thanks,
David
