MS switches running staking and OSPF

[SkyWong44]

Hi All:

As my understand from https://documentation.meraki.com/MS/Layer_3_Switching/MS_OSPF_Overview

OSPF and Warm Spare do not operate concurrently on a switch, which means eg. if I have 2 MS425 I can choose running ospf or Warm Spare.

I have two question

1. how about MS390? since MS390 support physical stacking, can it run sacking and OSPF operate concurrently?

1. how about Virtual stacking, can it run virtual  sacking and OSPF operate concurrently?

When the switches are stacking, you can run OSPF, because logically speaking they are like a single switch. In the case of Warmspare is that they will be working on active and standby.

Hi  alemabrahao

Thanks for your reply, for Physical stacking I believe the OSPF will work, but how about Virtual stacking on MS4xx? since behind the scenes, Virtual stacking is running STP .

[alemabrahao]

OSPF works on both, Physica and Virtual stacking.

Just a detail, the virtual stack server configures multiple ports at the same time, and the settings are not replicated from one switch to the other, that is, it is only possible to configure OSPF on the switch that has the Interfaces VLAN created.

So that would be only L2 connection between virtual stack member right ?

The MS390s are known to have a lot of stability issues.  I would avoid them.

Use Google for more information.
