1.You can use the parent tokens ex. %node:field-category:parent:parent:ab-name. You can use the parent token as many times as many levels deep you want
2.Also make use of the magic token (pb-join) to add all the taxonomy hierarchy automatically to breadcrumbs (ex. %node:field-categ:pb-join:name1 and %node:field-categ:pb-join:url).
