Suggestion: Makes no sense to me that the statement to remove ospf6
configuration is located in OSPF6D_NODE.
Moved to CONFIG_NODE next to matching define command.
install_element (VIEW_NODE, &show_ipv6_ospf6_cmd);
install_element (ENABLE_NODE, &show_ipv6_ospf6_cmd);
install_element (CONFIG_NODE, &router_ospf6_cmd);
+ install_element (CONFIG_NODE, &no_router_ospf6_cmd);
install_element (VIEW_NODE, &show_ipv6_ospf6_route_cmd);
install_element (VIEW_NODE, &show_ipv6_ospf6_route_detail_cmd);
