  • Cisco ASR 9000 Series Aggregation Services Routers

Known Affected Releases

7.3.1.BASE

Description (partial)

Symptom:
TE metric is not configured specifically under segment routing.
So IGP metric is used as TE metric as per TE norms,  in the Exended Link LSA.
Now, the IGP metric is changed. 
But TE metric remains same as the old IGP metric.

The issue here is that Exended Link LSA is not refreshed in case of IGP metric change.

Conditions:
1. Segment routing is enabled globally and inside ospf.
2. TE metric is not configured specifically under segment routing
3. IGP metric is changed after the network is stable.
