# Configure AS prepending on all other BGP sessions (Telcos/Uplinks)
# Optional, To influence incoming traffic and prioritize a peering link over another, you can use AS-path prepend. Simply prepend your ASN multiple times towards your Internet transit to make it less preferred. The longer AS-path will make the peering link more attractive. # Use your ASN in place of 65000
