Help with routing decision

Got BGP providing DGW and I have a static 0.0.0.0/0 with metric 240 so its last resort route

but

VIRTUAL ROUTER: vr_default (id 2)
==========
destination nexthop metric flags age interface next-AS
0.0.0.0/0 0.0.0.0 19 ~
0.0.0.0/0 202.74.32.69 ?B 612028 ASXXXX
0.0.0.0/0 202.74.32.71 240 A S ae3.10

for some reason the static is active over the BGP route ?

can't find a KB on how routing decides !

Support - well nearly 2 weeks in and the person doesn't understand ..

The metric will only be used when you have routes with the same protocol. So 2 statics, the one with the lower metric will be preferred.

For routes to the same destination, static will always be preferred over BGP as long as you have the default administrative distance configured. Administrative distance is what controls which routing protocol that gets used when the destinations are the same.

It's on the main tab of the virtual router on the right side.

Yes, i wasn't clear though. when i look at the runing stats for the vrtr and look at the route tab and look at routes - you can't see the admin dist there

or the cli , when i did a show route with detail it should show that so I don't have to guess / remember.

Thanks
