Maybe anothers network engineers may exchange yours experinece and help me to find a better network topology for my issue.

Lets explain current scenario.

We have bassically 3 networks in our enviroment.
- The core network
- The distribution network
- The access network / last mile

The question is related to distribution network layout. Nowadays it is a large bridged network with arround 50 devices (switches, wds, ap/bridge). All this devices are connected in the same broadcast domain and same ip network.

The access network, where our costumer are connected are separated routers with PPPoE concentrators. Thsi way, the access network and distribution network are in differente broadcast/collision domains.

So, I have a doubt if the bridge is a better choose for this scenario.

Changing this scenario to a routeable network , placing devices in different broadcast/collision domains can improve response time between core networtk and access network ?

what you think about ?

Thank`s

A 'fully bridged' network is perfectly OK for small networks, but if you wish the network to expand and be reliable by adding duplicated redundant links for example, you will indeed need to now change over to a fully routed solution.

To start, you can use static routing with manual entries in each router, but plan for using a more dynamic routing model, such as ospf and mpls as a final stage in your distribution network. If you need to distribute broadcast traffic (eg dhcp/ppoe) then consider eoip tunnels instead of bridging the whole network.

So, the answer is yes, go for routing before your network becomes a problem to manage!
