You can nest a paragraph parser inside a paragraph parser.   

I have done this with parsing “show interface” on a Cisco NXOS device.  

Top Paragraph ID line:   I name the paragraph parser “interface”

^Ethernet$string:interface is $string:intState

the ^ makes it the immediate start of line.   ill “^ “ if the line is indented.     

Then if I want the TX and RX I make a paragraph for them, with the parent being the “interface” paragraph parser.  

My ID line for TX is:

^ TX

Then create the variable lines under that.   Then repeat for RX.   

For the 2 load intervals (not really necessary as not sure where ill use them in intents)

I made 1 start line that covers both:

parent: interface
^ Load-Interval #$int:loadInt: $mstring:intervalTime

Ethernet1/1 is up
admin state is up, Dedicated Interface
  Belongs to Po101

This is pretty much the same as the above solution worded differently.  Create a new visual parser and add the first paragraph ID line for Logical Interface and create a variable(s) for whatever comes after Logical Interface on the same line.

Then create a second paragraph for the Address Flags with a variable for the flags after that (It looks like that needs to be an mstring since you can have more than one flag).

Then add in a Variable Line Pattern however you want it to parse the Destination line.

Then add the Logical Interface paragraph to the Address Flags paragraph as a parent. It should parse correctly but I am not sure how it will handle the second “Addresses, Flags: None” if it occurs under the same Logical Interface. All I can say is give it a try. 

I could think of a couple other ways without writing a Regex, but this seems to be the most direct.
