Cisco Bug: CSCsz51243 - NAT reassembled packet not fragment when VFR is off on ingress
Feb 01, 2017
- Cisco ASR 1000 Series Aggregation Services Routers
Known Affected Releases
Symptom: When fragments entering ASR with NAT ingress and egress configured, seem to come out of ASR as reassembled packets - and ingress virtual reassembly has been manually disabled. Conditions: When NAT ingress and egress is configured, VFR is automatically enabled on ingress and egress interfaces. If VFR is disabled from ingress interface manually, then fragments entering the ASR router will go out as reassembled packet from egress interface instead of getting fragmented as original fragments that entered the ASR.
