3Com 500 Network Router User Manual


 
Routing IP and IPX
A-15
This is achieved by the addition of a
/xx
number at the end of the
configured address. For example:
193.123.123.123/32
The /32
appended to the IP number indicates that all four of the bytes
are used and must have valid entries.
A /24
mask, for example:
193.123.123.0/24
means that only the first three bytes are to be recognized and used, and
the last byte can be ignored. In this case, any IP address appearing on the
locally connected LAN in the range 193.123.123.0 to 193.123.123.255 will
cause an autocall to be made to the destination network who’s name is
associated with that number in the ISDN Autocall table. The name is then
looked up in the ISDN Numbers table and a call made to the ISDN
number which has been assigned to that name.
