Hi everybody,
Please consider the following cases:
CASE A:
MX1-------MX2-----MX3--SUBNET Y
Above we are running OSPF , mpls family , rsvp on all interface.
MX1 is learning Y subnet via OSPF, we have statically defined RSVP LSPMX1-->MX3
Goal:
MX1 must use LSP to send traffic to Y.
I used OSPF short cut on MX1 and observed traffic is routed over LSPMX1->MX3
Unfortunately, I do not have North Star controller therefore do not know what to expect, I have following questions:
1) We delete statically defined RSVP LSPMX1-->MX3, and define it again but this time, we delegate the control to North Star Controller. i.e North Star will compute the best path and ask MX1 to signal it. Will in that case , using OSPF short cut on MX1 still acheive the above goal?
2) We delete statically defined RSVP LSPMX1-->MX3 LSP on MX1, we then provisioned RSVP based LSP MX1-->MX3 using North Star Controller, Will in that case , using OSPF short cut on MX1 still acheive the above goal?

CASE B:
MX1-------MX2-----MX3--SUBNET Y
Above we are running OSPF , mpls on all interfaces, but we are using segment routing this time i.e no RSVP.
We want to acheive the same goal i.e MX1 must use LSP(MX1-MX3) to send traffic to Y
Will OSPF short cut on MX1 still acheive above mentioned goal (MX1 must use LSP(MX1-MX3) to send traffic to Y ) if North Star is used to provisioned MX1-MX3 LSP using segment routing?
Thanks and have a good day!!
