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
