REP with HSRP

Hello all Network Guru,

I have set up the REP ring for 2 Redundant IE5000 industrial switches and 3 Access switches.

these two IE5000 switches have been configured as HSRP.

for the REP ring:

two ports in 1st IE5000 have been configured as Primary Edge Port and Edge Port.

two ports in 2nd IE5000 and rest of access switches have been configured as Transit ports.

I have tested and the network convergence time to drop SW01 and drop SW02 are almost the same ( 0 or 1 ping lost).

the testing is pinging from VLAN 10 in Access switch SW-A to Servers in VLAN 100. The result is promising and looks all good.

However, I still have doubt whether it is the best setup. 

I understand that the best solution is to stack up these two  IE5000 switches. see the link for details.

 

can anybody point out any potential issue for my setup?

Thank you.

Re: REP with HSRP

Hello,

 

as I understand it, horizontal stacking is mainly used to connect (via the 10G ports) IE switches that are physically far apart. Is this your situation ? Otherwise, your REP/HSRP configuration looks by the book (as outlined in the document attached)...

Re: REP with HSRP

Thanks, Georg

ironically, both Distribution switch SW01 and SW02 are in the same server and network panel.

 

Figure 7 in the file you mentioned on page 17 gave me the idea.

Why not configure the edge ports in other access switches instead in the distribution switches! The edge ports do not have to be in the distribution switch!

so the ports in SW01 and SW02 will be the transit ports,

the port Gi1/1 in SW-A will be the primary edge port and

the port Gi1/1 in SW-C will be the (secondary) edge port.

see the revised architecture. I highlighted what has been changed in the yellow box.
