Default route (IPv4) demolished by destroying clone (gif/gre) interface

[Darryl Yeoh]

Hi lists,

While destroying gif interface, I notice it also removes IPv4 default route. Has anyone else
encountered this ?

Command:

# netstat -rn -f inet
Routing tables

Internet:
Destination        Gateway            Flags    Refs      Use  Netif Expire
