Thursday, November 5th, 2009Rapid STP (RSTP) RSTP was developed to provide a faster converging alternative to STP, and is defined in IEEE 802.1w. Like STP, RSTP can be applied as a single instance or per VLAN. A root is elected by lowest bridge ID, as in 802.1D STP. Sorry you have no rights to view this post! [This [...]
CCNP BCMSN Notes – Spanning Tree Configuration
Tuesday, November 3rd, 2009Root Bridge Configuration The root bridge should be positioned centrally in the network to ensure the spanning tree forms in a predictable manner. Two bridge ID formats are available: 802.1D Standard – 16-bit priority + unique MAC address for the VLAN 802.1t Extended – 4-bit priority multiplier + 12-bit VLAN ID + non-unique [...]
CCNP BCMSN Notes – Traditional Spanning Tree Protocol
Tuesday, November 3rd, 2009STP is defined in IEEE 802.1D. BPDUs STP messages are carried by Bridge Protocol Data Unit (BPDU) frames; BPDUs are multicast to 01:80:c2:00:00:00. BPDU types: Configuration – Used for spanning-tree computation Topology Change Notification (TCN) – Used to announce changes in the network Sorry you have no rights to view this post! [This [...]
