Caslow p.90. "When you have a frame relay configured on sub-interfaces, you remove the need for manual mapping statements for NBMA PVC connections. PtoP remove the need for mapping since only one destination at the other end." Ok, this makes sense and sounds like normal ppp serial connection definition as well. No mapping needed because router assumes single connection on each end of link.
How does this impact what layer 2 and layer 3 address info is included in each outgoing frame on each end? What about source addresses? So, IOS and the interface include or not include addresses in frame relay packets differently depending on whether it is main interface or sub-interface? Also, from same page "Dedicated PtoP connections,....no need for mapping procedures....whatever the network layer address is on the local PtoP interface, the remote network layer address must match". Usually not something to dwell on, but the line about the network layer address "must" match got me thinking. What exactly does this mean? The remote IP address must be "match" in the sense that both IPs and both masks "match" the same subnet?
