Also, strict EROs are used when constraint based LSPs
are built using, for example, RSVP and CSPF in order
to build the LSP across a the same path that was
'reserved' using RSVP.

You might use loose EROs when you are manually
building your LSPs and want a balance between control
of the path and resiliency.

Lars Higham
