MLAG configuration

[Giuseppe_Montan]

Good evening, we are going to change an Exnterasys  S4 with 2 x590 plus 4 v400.

Now I have only one IP address configured.

The question is whether the whole core can have a single IP address as if it were a chassis or should I consider them different switches ?

thanks in advance

Thanks to all. we used the second option, 2 X590 in MLAG, 4 V400 connected with 2 links to X590.

We connected also 5 X440 with 2 links in LACP ( X440 -LACP   -→    X590-MLAG ).

Stefan,

You’re right, “As of 30.6: No, stacking cannot be enabled with VPEX enabled.”

For example, If I want to configure the port 10 in core B I have to connect to ipaddress of core B or I can configure only one IP for all Switches ( like Stacking ) ?

If you go for the second option, then you have two single switches and therefor need to connect to the Switch where you want to configure a port. If you want to configure MLAG Ports and need the same config on the same port on both switches you can make use of the orchestration feature.

If you stack them (option 1) you have one stack with one IP.

I don’t think that stacking and VPEX is compatible? https://gtacknowledge.extremenetworks.com/articles/Q_A/Can-Extended-Edge-Switching-VPEX-and-stacking...

Giuseppe,

There is no correct or uncorrect option.

There are options that meet your needs better than others

If you stack them (option 1) you have one stack with one IP.

If you cluster them (option 2) you have two switches with two IPs.

The result depends on the level of redundancy you want to achieve vs. operational effort.
