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
