SD-WAN Cisco, advertising default route to branch

Hi guys, i have two vEdges (HQ and branch), i want vEdge-1 to advertise a default route for service VPN-1 to vEdge-2, and at the same time i want vEdge-1 to NAT using "ip route 0.0.0.0/0 vpn 0"

Here is my config for service vpn-1

vpn 1

name Service-VPN-1

interface ge0/1

description Lan-Link-1

ip address 10.1.55.1/24

no shutdown

vrrp 56

priority 150

ipv4 10.1.55.3

!

!

interface ge0/2

description Lan-Link

ip address 10.1.66.1/24

no shutdown

!

ip route 0.0.0.0/0 vpn 0

omp

advertise ospf external

advertise connected

advertise static

advertise network 0.0.0.0/0

---------------------------------------------------------------------

vEdge-2:

vpn 1

name Service-VPN-1

interface ge0/1

description Lan-Link

ip address 10.2.1.1/24

no shutdown

!

omp

advertise ospf external

advertise connected

advertise static

!

and if i check vEdge-2 routing table, i cant find a defaut route advetised from vEdge-1.

i even advertised a default route frm my Core Switch that is connected to vEdge-1. and still vEdge-1 wouldnt redistribute that default route to vEdge-2

i know there are workarounds using DIA, but i really just want to advertise a default route to vEdge-2 without using default route to null0 "ip route 0.0.0.0/0 null0"

Thank you
