Description: If IS-IS is operating at both level 1 and level 2, this field indicates how IS-IS should decide whether to set the attached bit in its level 1 LSP.
- 'attachNoOverlapOrRedist' indicates that the attached bit should be set if either of the following are true. - The IS can reach at least one other area (the IS is adjacent with a L2 router whose area addresses do not overlap with the area addresses we know about at L1). - The IS is redistributing one or more external routes into the AS.
- 'attachNoOverlapOnly' indicates that the attached bit should be set only if the IS can reach at least one other area.
- 'attachSet' indicates that the attached bit should always be set.
- 'attachClear' indicates that the attached bit should never be set.
What is prvtIsisSysSetAttached?
This controls the logic the router uses to decide whether to set the ATT (attached) bit in its own level-1 LSP when running at both levels. For example, attachSet always sets the bit and attachClear never does, while the other two options tie it to whether the router can actually reach another area or is redistributing external routes, giving finer control over how level-1-only routers get steered toward this one as a default exit.
