OSPF Default Route

Hi All

Working through the IE Vol 1 Version 5 workbook I see this in the notes:

"without additional arguments on the command the default route would have
been advertised as a Type-2 External route with a metric of 20"

I tested this out, but I see the metric as 1. Is 20 a mistake in the IE
document or did I miss something?

Rack1R6#show run | sec router ospf
router ospf 1
 log-adjacency-changes
 network 0.0.0.0 255.255.255.255 area 0
 default-information originate always

Rack1R4#show ip route ospf
<...>
O*E2 0.0.0.0/0 [110/1] via 155.1.146.6, 01:08:39, FastEthernet0/1

Rack1R4#show ip ospf database external 0.0.0.0
