Hi,

Yes, it is possible to use Azure SDK for Python to list routes in BGP sessions established in Azure Virtual Network Gateway.

You can use the azure.mgmt.network package from the Azure SDK for Python to interact with Azure Virtual Network Gateway and retrieve information about the BGP sessions and the routes advertised through them. Specifically, you can use the BgpServiceCommunity and VirtualNetworkGatewaysOperations classes from the package to achieve this.

Here is a sample snippet :



from azure.common.credentials import ServicePrincipalCredentials
from azure.mgmt.network import NetworkManagementClient
from azure.mgmt.network.v2021_03_01.models import BgpServiceCommunity

# Authenticate with Azure using Service Principal credentials
creds = ServicePrincipalCredentials(
    client_id='<client_id>',
    secret='<client_secret>',
    tenant='<tenant_id>'
)

# Create a Network Management client
network_client = NetworkManagementClient(creds, '<subscription_id>')

# Get the Virtual Network Gateway resource ID
gateway_name = '<gateway_name>'
gateway_resource_group = '<gateway_resource_group>'
gateway = network_client.virtual_network_gateways.get(gateway_resource_group, gateway_name)
gateway_id = gateway.id

# Get the BGP service communities for the Virtual Network Gateway
bgp_communities = network_client.bgp_service_communities.list_by_virtual_network_gateway(gateway_id)

# Iterate over the BGP service communities and print the routes advertised through each BGP session
for bgp_community in bgp_communities:
    print(f"Routes advertised through BGP session {bgp_community.name}:")
    routes = network_client.virtual_network_gateway_routes.list_by_virtual_network_gateway_and_peer(
        gateway_resource_group,
        gateway_name,
        bgp_community.peer,
        BgpServiceCommunity(bgp_community.name)
    )
    for route in routes:
        print(f"- {route.address_prefix}")

Hello @Mituś Wojciech ,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

I understand that you would like to know if it is possible to use Azure SDK for Python to list routes in BGP sessions established in Azure Virtual Network Gateway.

It should be possible to use Azure SDK for Python to list routes in BGP sessions established in Azure Virtual Network Gateway.

First, you'll need to authenticate and create a "NetworkManagementClient" object, which you can use to interact with Azure networking resources.

Refer: https://learn.microsoft.com/en-us/python/api/azure-mgmt-network/azure.mgmt.network.v2022_05_01.networkmanagementclient?view=azure-python

Then to list the BGP routes learned by a virtual network gateway, you'll need to use the "begin_get_learned_routes" method of the "VirtualNetworkGatewayConnectionsOperations" class.

Refer: https://learn.microsoft.com/en-us/python/api/azure-mgmt-network/azure.mgmt.network.v2022_05_01.operations.virtualnetworkgatewaysoperations?view=azure-python

https://learn.microsoft.com/en-us/python/api/azure-mgmt-network/azure.mgmt.network.v2022_05_01.operations.virtualnetworkgatewaysoperations?view=azure-python#azure-mgmt-network-v2022-05-01-operations-virtualnetworkgatewaysoperations-begin-get-learned-routes

"begin_get_learned_routes" operation retrieves a list of routes the virtual network gateway has learned, including routes learned from BGP peers.

You'll need to provide the resource group name and the name of the virtual network gateway to list its learned routes.

Kindly let us know if the above helps or you need further assistance on this issue.

Please "Accept the answer" if the information helped you. This will help us and others in the community as well.
