Cisco Bug: CSCvs25893 - EVPN with Type-1 ESI: Service Carving re-elected upon process restart l2vpn_mgr
Sep 02, 2020
- Cisco ASR 9000 Series Aggregation Services Routers
Known Affected Releases
Release-note Symptom: On process restart, some EVI moves from non-elected to elected then move back to non-elected. This could lead momentary traffic duplication. Conditions: Two PE routers in EVPN A/A with ESI Type-1 (ie ESI learnt via lacp mac-id). Both boxes operate in default service carving mode (modulo). Do a process restart and some EVI could move from non-elected to elected then move back to non-elected and this could lead momentary traffic duplication.
