Network Routing Information

The following is part of a Sniffer trace .

What I need to know is if anyone can tell what the Rouint control number mean?

RI: —– Routing Indicators —–
RI:
RI: Routing control = 82
RI: 100. …. = All-routes broadcast, non-broadcast return
RI: …0 0010 = RI length is 2
RI: Routing control = 50
RI: 0… …. = Forward direction
RI: .101 …. = Largest frame is 11407
RI: …. 000. = Extended frame is 0
RI: …. …0 = Reserved
RI:

Thanks
