az network route-table

az network route-table create/update should accept a new --disable-peering-route parameter with values None (default) or All.
az network route-table show/list should display the disablePeeringRoute property in the output.

Is your feature request related to a problem? Please describe.
The Azure Network RP has added a disablePeeringRoute property to Route Tables in API version 2025-07-01, but the CLI commands do not yet expose this capability.

Describe the solution you'd like

Add support for the new disablePeeringRoute property in Route Tables. A new optional property disablePeeringRoute has been added to RouteTable. This is an enum with two values:

None (default): Peering routes are enabled on the route table.
All: All peering routes are disabled on the route table.

az network route-table create/update should accept --disable-peering-route {None, All}
az network route-table show/list should display the property in output
