Where to config "OSPF IGP shortcuts" & "traffic engineering shortcuts"?

koala0808 · December 2011

Hi Mate,
I encountered an issue regarding shortcuts when I read the Junos config guide in the following link:
http://www.juniper.net/techpubs/software/junos/junos94/swconfig-routing/configuring-ospf-igp-shortcu...
It mentioned that in the "NOTE" section:
==============================
Note: Whenever possible, use OSPF IGP shortcuts instead of traffic engineering shortcuts.
==============================
So I am just confused with "OSPF IGP shortcuts" and "traffic engineering shortcuts" as I can ONLY find 1 place to config "shortcuts":

under the [edit protocols ospf traffic-engineering shortcuts] hierarchy level

Is above the "OSPF IGP shortcuts" or "traffic engineering shortcuts"?
So could any one pls kindly bring some light to me as to how to configure the "OSPF IGP shortcuts" and "traffic engineering shortcuts" as Junos config guide noted?
Thanks in advance.
Kind regards
Leo Gu

I think they may be referring to this:

[edit]
user@host# set protocols mpls traffic-engineering ?  
Possible completions:
  bgp                  BGP destinations only
  bgp-igp              BGP and IGP destinations
  bgp-igp-both-ribs    BGP and IGP destinations with routes in both routing tables
  mpls-forwarding      Use MPLS routes for forwarding, not routing

So you mean the "traffic engineering shortcuts" is the same as you demonstrated while the "OSPF IGP shortcuts" is what I posted originally as follows?

under the [edit protocols ospf traffic-engineering shortcuts] hierarchy level

Thanks.
