Unit 1: Network Infrastructure
This will allow you to demonstrate your networking skills, knowledge, and abilities, with a focus on enterprise-level switching, routing, and multicast components that support cross-platform (inter)operability and integration with the most recent software-defined technologies.
It is only possible to employ Bridge Assurance with RPVST+ and MST, and it is only utilized on point-to-point links. Rules that govern the transmission of BPDUs are altered by Bridge Assurance. When it is activated on a port, the port will always send BPDUs during each and every Hello interval. This is true regardless of whether the port is performing the job of a Root, Designated, Alternate, or Backup port. To put it simply, BPDUs are essentially Hello messages that are sent between pairs of connected switches.
If a Bridge Assurance port does not get any BPDUs, it will be placed in a BA-Inconsistent blocking state until it starts receiving BPDUs again. Bridge Assurance ports are required to receive BPDUs. In order to prevent loops from being introduced by malfunctioning switches when they quit participating in RPVST or MST, Bridge Assurances helps to assure that a topology is clear of loops.
