Can we create an multiple HUB in our existing sdwan network

[MGSAZAM]

Hi,

Introduction:

I have a SDWAN setup in which I am already using HUB & SPOKE scenario. Like whole network we distributed in 4 zones

Zone-A ,Zone-B, Zone-C, Zone-D

> Every Zone having multiple SD-WAN sites

> For Inter-Zone communication is happening via HUB-1( located in Zone-A at DC)

>For Intra-zone communication is happening directly  

Now the new requirement is:

We have taken a cloud service(example ip:1.1.1.1/32) which is hosted on our one of the Zone-A site-X.

Question:

can we configure the site-X as HUB-2 only for the single destination (ip:1.1.1.1/32), and rest of the traffic should go via  existing HUB-1.

Hi,

Yes, You can achieve this by centralized policy.

You have to create a custom topology to have 2 Hubs using TLOC IDs and Site IDs.

Since, 1.1.1.1/32 will only be learned from Hub-2 by all other spokes, it’ll become a transit path and for the rest of the destinations, Hub-1 will be used.
