Example: Booting from a Network Server over X.25

Over X.25, you cannot boot the router from a network server via a
broadcast. Instead, you must boot from a specific host. Also, an

x25

map

command must exist for the host that you boot from. The

x25

map

command is used to map an IP address into an X.121 address.

There must be an

x25 map

command that matches the IP address

given on the

boot system

command line.

boot system gs3-k.100 172.18.126.111

interface Serial 1

ip address 172.18.126.200 255.255.255.0

encapsulation X25

x25 address 10004

x25 map IP 172.18.126.111 10002 broadcast

lapb n1 12040

clockrate 56000

In this case, 10002 is the X.121 address of the remote router that can
get to host 172.18.126.111.

The remote router must have this

x25 map

entry:

x25 map IP 172.18.126.200 10004 broadcast
