network doubt

Dear golegas, some time ago I started a small business to serve the internet to people in the neighborhood and spend time began to grow. now with 500 customers, the network is all in bridge and beginning to worry. I participed in mikrotik course but still have doubts, questions of how to make the network architecture. I’m not a North! I need help from you experienced to get an idea of how to isolate clients, use or not pppoe etc.



to be honestly i think network bridge is being trouble like this:

ping 172.16.0.17
HOST SIZE TTL TIME STATUS
172.16.0.17 56 128 5ms
172.16.0.17 56 128 68ms
172.16.0.17 56 128 13ms
172.16.0.17 56 128 10ms
172.16.0.17 56 128 7ms
172.16.0.17 56 128 24ms
172.16.0.17 56 128 4ms
172.16.0.17 56 128 42ms
sent=8 received=8 packet-loss=0% min-rtt=4ms avg-rtt=21ms max-rtt=68ms

[admin@MikroTik] > ping 172.16.0.48
HOST SIZE TTL TIME STATUS
172.16.0.17 56 128 39ms redirect host
172.16.0.17 56 128 77ms redirect host
172.16.0.17 56 128 30ms redirect host
172.16.0.17 56 128 10ms redirect host
172.16.0.17 56 128 76ms redirect host
172.16.0.17 56 128 15ms redirect host
sent=6 received=0 packet-loss=100%

as you can see if i ping one customer ping is redirect to other one !

Hi,

I suggest you begin to plan to switch you network to a routed one.

It will save you from those strange issues with a bridged network.

Also then you can install backup links and use OSPF for full duplex links with redundancy.
