Calc broadcast domain

[AndyCheong99584]

Hi, would like to understand how should i calc the no of broadcast domain given in this diagram? Given that the routers is layer2 capable and is supporting the STP function of the mesh network of switches connected.

Hi,

There is insufficient information to tell how many broadcast domain in the given diagram.

It depends on the interface's setting on routers, and VLAN setting on core switches.

hi,

Apologies for the lack of info and knowledge, what kind of information should i provide on the routers and switches to make a better representation? Thanks.

Hi,

You may gather the "show run interface <INTERFACE-ID>" information on each connected interface for each device.

You also need the "show vlan" on both of the core switches to determine the number of broadcast domain if there is any trunk link in your topology.
