In a Spanning Tree Protocol (STP) network, theRoot Portis selected on each switch (except the Root Bridge).
The Root Port is the port with thelowest path costto the Root Bridge. If there is a tie in path cost, the following criteria are used in sequence to break the tie:
Steps for Root Port Election in Sequence:
RPC Comparison (Root Path Cost):
The port with thelowest Root Path Costis preferred.
Root Path Cost is the cumulative cost of the path to the Root Bridge.
Peer BID (Bridge ID) Comparison:
If the Root Path Costs are equal, theBridge IDof the connected switch (peer) is compared.
The port connecting to the switch with thelower Bridge IDis preferred.
Peer PID (Port ID) Comparison:
If the Bridge IDs are equal, thePort IDof the peer's sending port is compared.
The port connecting to thelower Port IDis preferred.
Local PID (Port ID) Comparison:
If all else is equal, theLocal Port IDof the switch is used.

NEW QUESTION # 346
In BGP, the AS_Path attribute records the numbers of all ASs that a route passes through from the local end to the destination in the vector order.
Which of the following statements is false about the attribute change during route transmission?

A. When advertising the route to an EBGP peer, the BGP speaker creates an AS_Path carrying the local AS number in the Update message.
B. When advertising the route to an IBGP peer, the BGP speaker creates an empty AS_Path in the Update message.
C. When advertising the route to an EBGP peer, the BGP speaker adds the local AS number to the end of the AS_Path.
D. When advertising the route to an IBGP peer, the BGP speaker does not change the AS_Path attribute of the route.

Answer: B

Explanation:
Option A is false. When advertising a route to an IBGP peer, the BGP speaker does not modify the AS_Path.
It simply advertises the route as-is, preserving the AS_Path learned from EBGP.
Clarification of the options:
B is correct: When a route is sent to an EBGP peer, the local AS is prepended to the AS_Path.
C is correct: The AS_Path begins with the local AS when a new route is advertised to an EBGP neighbor.
D is correct: IBGP does not modify AS_Path when passing routes within the same AS.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"BGP speakers prepend their AS number to the AS_Path only when advertising to EBGP peers. IBGP peers do not alter the AS_Path." (Chapter: BGP Path Attributes - Section: AS_Path)
