Enable OSPF or IS-IS on the tunnel interface of the MPLS TE tunnel before configuring automatic
route advertisement.
To use automatic route advertisement, specify the destination address of the TE tunnel as the LSR
ID of the peer and advertise the tunnel interface address to IGPs, such as OSPF and ISIS.

If no IGP type is specified, the
configuration applies to both
OSPF and ISIS by default.
