· XXXXXXXXXXPC3-2: XXXXXXXXXX/24 gateway XXXXXXXXXX
· …
· XXXXXXXXXXPC3-200: XXXXXXXXXX/24 gateway XXXXXXXXXX
And the IP addresses used for links between networks are:
· XXXXXXXXXXR XXXXXXXXXX/24) links to R XXXXXXXXXX/24)
· XXXXXXXXXXR XXXXXXXXXX/24) links to R XXXXXXXXXX/24)
· XXXXXXXXXXR XXXXXXXXXX/24) links to R XXXXXXXXXX/24)
