----------------------------------------------------
L3 Protocol       : xxxx
L4 Protocol       : yyyy
Destination IP    : x.x.x.x
Source IP         : y.y.y.y
Port/Type         : aaaa
Source Port       : bbbb
Is Fragment       : 
Is SYN            : 
Interface         : 
VRF-ID            : 
P                 : 
L                 : 
Dest Addr         : 
Flow Type         : UDP
----------------------------------------------------
L3 Protocol       : xxxx
L4 Protocol       : yyyy

L                 : 
Dest Addr         : 
Flow Type         : NTP
----------------------------------------------------
this i need to parse based on the flow type
means if my input for flow type is NTP
the output should look like

L3 Protocol       : xxxx
L4 Protocol       : yyyy
Destination IP    : x.x.x.x
Source IP         : y.y.y.y
Port/Type         : aaaa
Source Port       : bbbb
Is Fragment       : 
Is SYN            : 
Interface         : 
VRF-ID            : 
P                 : 
L                 : 
Dest Addr         : 
Flow Type         : NTP


Could you please guide me to achieve this


Thanks in advance
