Quick question guys. For exam and real world use purposes. What is the more acceptable way to enable SRTE for ISIS?
There are two options I have been testing and both of them seem to enable SRTE. Thanks!
Option 1:
router isis SP
address-family ipv4 unicast
router-id loopback0
Option 2:
router isis SP
address-family ipv4 unicast
mpls traffic-eng level-2
mpls traffic-eng router-id loopback0
Solved! Go to Solution.

Hi @jpl861 ,
Option 2 came from the RSVP-TE configuration and was initially required to configure SRTE. Option 1 is the preferred way to configure SRTE in more recent IOS-XR versions, as per the configuration guide.

Thank you. I actually tested this months ago and if I remember it right, when I used OSPF as the IGP the SRTE policy went up right away and I didn't even define router-id. I also didn't try to configure the mpls te configurations under the routing process because I also knew it is for mpls-te/rsvp-te. I also didn't see option 1 in any of Clarence's SR book/documentation so I really wondered why putting mpls-te configs under the routing process also enables SRTE.
