Compatibility between EAPS and G.8032 ERPS

[Ken_Johnathan]

hi Experts,

Can EAPS interoperable with G.8032 ERPS?

From P.68, it mentions:

• Basic interoperability with EAPS with G.8032 acting as an access ring. Flush notifications will be sent Link monitoring using CFM or native local link monitoring methods.

it shows that it is interoperable, just wanna know more detail on that.

if a network running EAPS and there is some old device with G.8032, just wanna know if that old gear can interoperable with the EAPS. thx.

Hi P,

Thanks for the prompt reply.

as i just planning for a migration from EAPS to ERPS as below, the new core supports ERPS only.

step 1: connect the new core as ERPs to the existing EAPS core:

Step 2: migrate TOR with 1 uplink to new core (erps) and 1 uplink still connecting to existing core. (eaps)

is it possible? Or i need to configure the ERPS on the existing TOR and Core too? thx.

Actually, i just wanna achieve a migration without down time. thx.

Hello Ken

the two can interoperate if one is a sub-ring of the other. They will send will send flush notifications. You cannot create one ring with some nodes using EAPS and others using ERPS/G.8032.

Does that help?
