Question regarding bgp default routes

what would cause a router to have a bgp default route of 0.0.0.0 with a next hop of 0.0.0.0 and weight of 0?

usually when a router originates a default route the weight in the bgp routing table is 32768...why would that change to zero?

A weight of 0 usually means that it was originated on another router.

Only thing I can think of is a route-map changing the weight of your default route.

Can you post your config?

remote router

router bgp 64512
bgp log-neighbor-changes
bgp confederation identifier 65535
no bgp default ipv4-unicast

address-family ipv4
neighbor 192.168.1.1 activate
neighbor 192.168.1.1 default-originate

My routers address is 192.168.1.12 and I have a similar configuration on it

I found out the reason why...........

since I'm sending default routes both ways, the 0.0.0.0 next hop with a weight of 0 is for loop prevention
