hi hunt,

1. frame-relay map statements to point to other spokes is to acheive the
connectivity between 2 spoke. coz there are all on same subnet, and no
physical connection between two spoke their address need to be mapped to
hub.

2. changing the network type is used to form ospf adjacency. since ospf
only form adjacency only if the network types are same.
