  2. Run interface virtual-template vt-number

    A virtual template is created or a virtual template view is displayed.

  3. Run ip address ip-address { mask | mask-length }

    An IPv4 address is configured for the virtual template.

  4. (Optional) Run ppp authentication-mode { auto | chap | pap }
