Gurus,
Im announcing a default route on my client and i got this on the remote side .
r> 0.0.0.0

Hello Jeff,
a default route is represented as:
0.0.0.0/0
if you want to know if a router has a default-route in its routing table do:
sh ip route 0.0.0.0
So I think that what you see on the remote site can be correct: try to use the command above to check it
Hope to help

Here is the result on the remote side
Routing entry for 0.0.0.0/0, supernet
Known via "static", distance 1, metric 0, candidate default path
Routing Descriptor Blocks:
* x.x.x.x
Route metric is 0, traffic share count is 1

hello Jeff,
you have a static route for default on the remote that is overriding for its lower AD (administrative Distance) the route sent by the routing protocol in use (if any)
the entry will be
ip route 0.0.0.0 0.0.0.0 x.x.x.x
if you want to use the route of dynamic routing protocol you need to make the static a floating static route
do the following:
! CAUTION here or you can miss the remote end
ip route 0.0.0.0 0.0.0.0 x.x.x.x 200
! this adds a floating static route with AD 200 this is as a last resort if the default route in the routing protocol is missing
no ip route 0.0.0.0 0.0.0.0 x.x.x.x
! this will delete the first static route
from now you should see the default route coming from the routing protocol.
If for any reason this is missing the floating static route will be installed and you can still reach the remote router.
Hope to help

Hi Giuseppe,
My client want to received both default route on 2 providers and acheived load sharing, is this possible ?

Hello Jeff,
this is possible if:
the two 0.0.0.0/0 will be learned with the same AD and metric (if applicable).
If the parameters match both routes will be installed in the routing table and you will achieve load-balancing as well
if using eBGP to have both paths installed you will need
router bgp yourASN
maximum-paths 2
Hope to help
Giuseppe
