Path type
Specifies the type assigned to the routes imported into OSPF.Possible values:
External type 1
The OSPF metric is formed from the redistribution metric or constant metric + the total path metric used to reach this ASBR.
Note: In the OSPF routing algorithm of routers, type 1 routes are generally preferred over type 2 routes.
External type 2
The OSPF metric is formed from the redistribution metric and/or the constant metric.
External route tag
