Depends on the hardware and software interface descriptor block (IDB)
limits for your platform:
"Each tunnel interface definition (such as Universal Transport
Interface - UTI, Generic Routing Encapsulation - GRE, Multiprotocol
Label Switching Traffic Engineering - MPLS TE, or Any Transport over
MPLS - AToM) consumes an HWIDB plus one SWIDB per tunnel, plus an
additional SWIDB for each additional sub-interface (for example, Frame
Relay PVC) being tunneled. The tunnel IDBs are in addition to the
original interface(s) being tunneled."
