Netmask
– Network mask, used during routing to determine the portion of the

Point-to-point frame relay IP connections will display a
Netmask

Destination Mask
value for Host
IP routes. (The
NetMask

Each entry is two lines on the screen, with the
Netmask
on the second line,
under the associated
Destination
