is using crs309 for Hsgmii safe

Mon May 15, 2023 1:40 am

Hello,

first my english is bad ... i know it and i'm sorry............

I prefer ask just to be 100 % certain before i make a mistake......

i have a ccr2004-16g-2s+PC not compatible with hsgmii 2.5 Gb and i want to use all 2Gbit down link of my provider with a FS Gpon (GPON-ONU-34-20BI)
The Gpon only synchronize at 1Gbit in the ccr2004 ( no auto-negociation full speed at 2.5 GBit but it doesn't work)

The ccr2004 has firewall etc...

I have a crs309-1g-8s+IN in my local network. This crs309 fully support this sfp Gpon with 2.5gb speed.

The solution i found on lafibre.com is to make a bridge between two ports (sfp1 and sfp2) of the crs309 (no ip address - just a bridge)
sfp 1 : module GPON-ONU-34-20BI
sfp2 : Dac connect to the Wan port of the CCR2004

so on the crs309 i will have 2 bridge : one with the onu (bridge_ONU) and the other bridge which is part of my LAN (brigde_LAN)

is it correct that i have no firewall rules to put on the crs309 ? The bridge with the ONU will only make a "passthrough" to the router ?
