NOF Indications
NN_TOPOLOGY_TG_INDICATION
Virtual routing node.
branch_aware
Specifies whether the node supports branch awareness, APPN Option Set 1120.
AP_NO
The node does not support option set 1120.
AP_YES
The node supports option set 1120.
4.17 NN_TOPOLOGY_TG_INDICATION
This indication is generated when a TG entry in a network node’s topology database is activated or deactivated.

4.17.2 Parameters
opcode
AP_NN_TOPOLOGY_TG_INDICATION
primary_rc
AP_OK
data_lost
Specifies whether any previous NN topology TG indications have been lost. If SNAplus2 detects a condition
that prevents it from sending an indication (for example an internal resource shortage), it indicates this by
setting the data_lost parameter on the next indication after the condition has cleared. Possible values are:
AP_YES
One or more previous NN topology TG indications were lost. Later fields in this VCB may be set to
zeros.
