Network requirements
For the GR-enabled switch, the GR method must be configured in the view of
■
the corresponding process. Additionally, the Neighbor State Machine (NSM)
must be in the FULL state.
Three switches Switch 8800 FamilyA, Switch 8800 FamilyB and Switch 8800
■
FamilyC are connected adjacently with each other. Switch 8800 FamilyA serves
as the Restarter, and Switch 8800 FamilyB and S8 500C serve as the Helper.
