All,

When configuring LSP's for access by route's on an IGP (i.e. OSPF) is it
better to advertise the IGP into BGP through a
policy statement (hence using inet.3 db) or enabling IGP LSP usage through
the 'traffic-engineering shortcuts' command ?

The policy statement exports OSPF into BGP group internal.

Also, will fast-reroute & CSPF still benefit IGP route's if the
traffic-engineering shortcuts command is used instead of policy ?
I guess then RSVP & LDP still applicable.

Cheers,

Neil.
