+Subject: [PATCH 3/3] ospfd: Support show intra-area network type in 'show ip
+ ospf route' command
+
+User can now use 'show ip ospf route detail' command to distinguish
+intra-area stub network and transit network.
+Transit network will be displayed as 'N T prefix ...'.
+
+NOTICE: Json output format has been changed, intra-area stub networks
+still has 'N' routeType, transit networks has 'N T' routeType. And
+'adv' (means advertise router) change to 'advertisedRouter'.
