  • Cisco ASR 9000 Series Aggregation Services Routers

Known Affected Releases

5.2.0.BASE

Description (partial)

This is part of fix to resolve CSCul47580. We need engine type to decide hashing algorithm on FIB PD. Currently, LSPV can send pak via fib_mpls_oam_lbl_hash_attr_st, and then fill in lb_args.lba_info.pak with that value. PI Fib needs to take into consideration that the packet pointer is passed.

Symptom:
LSPV Treetrace on ASR9K will not execute all ECMP paths.

Conditions:
This issue only happens in ASR9K due to a change in hashing algo.
