How to confiure MD5 key on BGP session in Azure gateway

François BELLEC 20

Hello.
I've setup a IPSec tunnel from Azure to my On-Premise router.
BGP is configured to exchange routes.
Even if it works fine, I want to configure MD5 key on this BGP connexion, but I can't find any settings on this.
Can you explain where I can setup this ?
Kind regards François.

You can do this for the IPsec tunnel, but you will have to do it via custom IPsec policy, see: https://learn.microsoft.com/en-us/azure/vpn-gateway/ipsec-ike-policy-howto

Hello.
Thank you for your answer, but my question is not about IPSec policies, but BGP.
What I need is to authenticate BGP peers with an MD5 key.
But I can't find this parameter.
Kind regards.
