The message age field in a BPDU transmitted by the root bridge is initialized to 0.Each other bridge will take the message_age value from BPDUs received on their root port andincrement this value by 1. The message_age thus reflects the distance from the root bridge.BPDUs with a message age exceeding max-age are ignored.STP uses the max-age value configured in the root bridge. This value is propagated to the otherbridges via the BPDUs.The no form of this command returns the max age to the default value.Default 20Parameters seconds — The maximum info age for the STP instance in seconds.Values: 6 — 40Item DescriptionSyntax max-age secondsno max-ageContext configure>service>vpls>stp(1 of 2)
