I have vyos 1.2.8 and have two ISPs configured on on-prem Vyos. From there I have setup two A/A site2site tunnels with Azure. And this is BGP over IPsec using VTI
On vyos my vtis are 169.254.21.9 & 169.254.21.13
While at Azure end 169.254.21.1 & 169.254.22.1
The subnet for on-prem network is 192.168.40.0/23 while at Azure Vnet is 10.1144.0/22
Now I have been asked by Azure team to add AS-PATH Prepend and I have below questions/confusion.
- This AS-PATH Prepend is going to be Import or export?
- I need to keep vti2 as my secondary link hence I am creating a route-map for neighbor 169.254.21.1
- Or will that be applied to 188.8.131.52?
Can someone please help me on this?
