Find the Root Bridge 1. Find the root bridge with the lowest Bridge ID. (Bridge priority and MAC address) 2. All the active ports on the Root Bridge become designated ports. Find the Root ports (One RP per switch) 1. Lowest cost to Root Bridge. 2. Lowest neighbor Bridge ID 3. Lowest neighbor port priority 4. Lowest neighbor internal port number. Note: 3-4 are only used if you have multiple links between two switches and if you tie with 1-2. Finding the Designated ports for LAN segments. 1. Find the switch that has the lowest cost to the root bridge. You do this by looking at the link between the switches. Which side has the lowest cost? Then that side of the link becomes the DP. 2. Which side of the link has the lowest BID 3. Lowest port priority 4. Lowest internal port number. Note: 3-4 are super rare for DPs. It's only if you have multiple links connected between two switches through a HUB! In this situation, you created a loop! This never happens in real networks. After you find the RPs and DPs all other ports become blocked.

The key point is that a switch doesn't understand IP addresses, only MAC addresses. Thus the router needs to find the destination MAC with ARP before it sends it to the switch. Then the switch can forward the frame out the right port. Yes, you'd think an IP address would be enough (Unique), but again switches don't understand IP so we need to find the MAC.

Note: 3-4 are only used if you have multiple links between two switches and if you tie with 1-2. Finding the Designated ports for LAN segments. 1. Find the switch that has the lowest cost to the root bridge. You do this by looking at the link between the switches. Which side has the lowest cost? Then that side of the link becomes the DP. 2. Which side of the link has the lowest BID 3. Lowest port priority 4. Lowest internal port number. Note: 3-4 are super rare for DPs. It's only if you have multiple links connected between two switches through a HUB! In this situation, you created a loop! This never happens in real networks. After you find the RPs and DPs all other ports become blocked. STP Costs 1. 100 for 10Mbps 2. 19 for 100Mbps 3. 4 for 1Gbps 4. 2 for 10Gbps

Find the Root Bridge 1. Find the root bridge with the lowest Bridge ID. (Bridge priority and MAC address) 2. All the active ports on the Root Bridge become designated ports. Find the Root ports (One RP per switch) 1. Lowest cost to Root Bridge. 2. Lowest neighbor Bridge ID 3. Lowest neighbor port priority 4. Lowest neighbor internal port number.

Cisco UDLD: https://www.youtube.com/watch?v=OyHqeXY8P-g I'm reverse engineering the protocol by looking at the packet capture. Please forgive me if something is wrong.

You will learn GRE and how to share those networks with EIGRP. Fun! Those IP addresses are getting to me. I'm repeating some. Ha.

Spanning tree protocol! How fun! Disclaimer: It may cause muffin cravings! And accuracy is not guaranteed, but I'll do my best! Find the Root Bridge 1. Find the root bridge with the lowest priority or MAC address. Sometimes called the Bridge ID. 2. All the active ports on the Root Bridge become designated ports. Find the Root ports (One RP per switch) 1. Lowest cost to Root Bridge. 2. Lowest neighbor Bridge ID 3. Lowest neighbor port priority 4. Lowest neighbor internal port number. Finding the Designated ports for LAN segments. 1. Between non-root switch segments, find the switch that has the lost cost to the root bridge. 2. Lowest BID 3. Lowest neighbor port priority 4. Lowest neighbor internal port number. STP Costs 1. 100 for 10Mbps 2. 19 for 100Mbps 3. 4 for 1Gbps 4. 2 for 10Gbps
