Sample dynamic NETID configuration

Figure 1 and Figure 2 are a sample dynamic NETID configuration.

Figure 1. Backup of a gateway NCP - part 1

Diagram that illustrates backup of a gateway NCP.

NCPA1 and NCPA2 are gateway NCPs. NCPA1 supports NETC and NETD; NCPA2 supports NETB. NCPA2 has an extra switched line defined.

Figure 2. Backup of a gateway NCP - part 2

NCPA1 link to NETD goes down. NETD dials NCPA2 to connect to NETA.

Following is the coding for the backup gateway NCP (NCPA2):

Notes:

Omit the NETID operand from the NETWORK definition statement.
Ensure that you have PATH definition statements defined for all the adjacent subareas. Thus, for the above coding, the adjacent subarea in NETD must be either 15 or 24.
