Cisco Bug: CSCsz42043 - OSPF originating orphan TE LSA
Feb 15, 2018
- Cisco IOS
Known Affected Releases
Symptom: OSPF may keep self-originated type-10 TE LSAs in its link state database that do not correspond to valid entries in the OSPF TE fragment table. These LSAs may duplicate valid link descriptions and confuse TE. In particular, the presence of duplicate link description LSAs can cause automatically computed FRR backup tunnels to flap and issue log messages like: 670113: Apr 26 04:02:27.999 GMT: %MPLS_TE-5-TUN: Tun18002: LSP path change nil for 18002_1, tunnel shutdown 670114: Apr 26 04:02:28.331 GMT: %MPLS_TE-5-TUN: Tun18002: LSP path change 18002_1 for nil, normal Conditions: This can only be seen if OSPF is being used to advertise a MPLS TE topology.
