Symptom: An ESP crash occurs for non fixed IOS-XE routers. If the ESP is integrated (ASR1001/ASR1002F/ASR1002X/4451/ect) the entire router will crash. Conditions: This symptom occurs when a existing NAT pool is unconfigured and re-configured with a new address. For example: no ip nat inside source route-map 105_NAT_MAP pool 105_NAT_POOL vrf CLIENT_105 overload no ip nat pool 105_NAT_POOL 10.10.10.1 10.10.10.1 netmask 255.255.255.252 ip nat pool 105_NAT_POOL 10.10.10.2 10.10.10.2 netmask 255.255.255.252 ip nat inside source route-map 105_NAT_MAP pool 105_NAT_POOL vrf CLIENT_105 overload The crash happens when the new NAT translations are created but the old translations still exist.
