=========================================================

currentily in my network there is no Redundancy as shwon in the attached file (Currnet Design)

I am going to make a new design as shown in the attched file (New Design)

so I need your opinion about the connection and configration between both cores if is L2 or L3 , also between access switch and Core switches

Note :- in the both ISP routers I am using BGP .

I Look forward to your opinion.

Thanks..

Hi,

looking on your new design I think it will be best for use Layer-3 redundancy between the core switches and the edge routers, for example you can use OSPF and BFD and gain a sub-second fail-over between them.

As for the access layer - does these switches are layer-2? where is the layer-3 for those hosts which connected to those switches?

Hi ,

Regarding  Layer-3 for those hosts , in my plan actually there are aournd 10 VLANs and will be created SVI for each one with GLBP protocol on both core switches ,

between the core switches and the edge routers will be Layer-3 through BGP .

my question which is the best for Layers between  both core switches for connection with each other?

as per this design on the each siwtches there are 2 uplink to both core switch but on of this links will be block  due to STP

Thanks..
