[AusNOG] Assistance with Cisco vPC configuration on 4 x Cisco Nexus 3000 switches

[Radek Tkaczyk]

Hi Jake,

That's something that I wanted to check if it was needed/recommended.

Can certainly put it in if it will help achieve better performance and redundancy

Thanks

Radek

Hi Radek,

Not personally familiar with vPC, more so Arista MLAG and Juniper MC-AE.

In the diagram there isn't a peer link between 13 & 14 - is that a mistake in the diagram or the actual design?

If you intend to build 2x20G bonds to two standalone nexus switches, that'll work fine.

If you are trying to achieve a 40G bowtie between the two pairs I'm fairly certain that won't work (unless Cisco has some special black magic to transport signalling/MAC synchronisation over the bond itself).

Cheers,
Jake

Hi Guys,

I have a need to configure vPC on 4 x Cisco Nexus 3000 switches at one of our data centres - a design that we will replicate to other data centres as well.

I think I have the config down pat, but I'd like someone with another pair of eyes to go over it with me to ensure it's 100% correct.

Is there anyone who can give me a hand here with this configuration, happy to pay for someone's time to go over it to ensure we are doing this correctly.

The Physical setup that I'm looking for:
