When configuring X.25, you are required to configure a set of X.25 map statements that identify the X.121 address that corresponds to each router on the X.25 network. When making this configuration, do not forget to include the "broadcast" keyword on the end of the command. This keyword tells the router to forward a copy of any broadcast packet to the named X.121 address. Without this keyword, you will find that your routing updates are not being sent to the remote routers and that connectivity exists only to the remote router's X.25 interface.
