BGP Routing Mode Configuration
BGP Routing Mode in IPT Service Delivery
BGP Routing Mode enables automatic route learning and adjustment using routing protocols of BGP (Border Gateway Protocol). In this mode:
Customers must have their own IP addresses.
The network automatically adapts to topology changes.
Ideal for complex and frequently changing network architectures.
Supports real-time route optimization and failover.
Requires more sophisticated network equipment and configuration.
Prerequisites
Please Authorize ASN or AS-SET required for BGP interconnect first.
Delivery times may vary by location. The actual interface display shall prevail. Thank you for your patience.
Procedures
Authorized ASN for the BGP peering
Our ASN, 21859, will be used on our side of the BGP session, with a maximum accepted route count of 1,000 to prevent route leaks caused by misconfiguration or malicious behavior.
BFD (Optional)
Check Enable BFD (optional) to activate BFD, enhancing routing reliability.
Bidirectional Forwarding Detection (BFD) is a network protocol provides rapid detection of link failures in the forwarding path in both directions.
Minimum Transmit Interval (ms)
The minimum send interval, in milliseconds, at which the local device sends BFD control packets to its peer. Lower values result in faster failure detection but increase network overhead.
Minimum Receive Interval (ms)
The minimum receive interval, in milliseconds, that the local device is willing to receive BFD packets from its peer. This indicates how frequently the peer is expected to send control packets.
Detection Multiplier
Defines the number of missed BFD packets before declaring the connection down. For example, with a detection multiplier of 3 and a receive interval of 300 ms, the system will consider the link down if it doesn't receive BFD packets for 900 ms. Higher values reduce the chance of false alarms but delay failure detection.
MD5 Authentication (Optional)
MD5 authentication is a security mechanism used in BGP routing protocol to verify the identity of peers and protect routing sessions from unauthorized access or tampering.
The MD5 key must be identical on both ends of the BGP session.
Mismatched or missing keys will cause the session to fail.
Routing
1. Select Inbound Routing Type
Choose how your device receives routes from the BGP peer:
Full Route Receives all possible BGP routes from the internet.
Recommended for backbone networks or routers that require full visibility into global routing.
Default Route Receives only a default route (0.0.0.0/0).
Suitable for smaller networks or when external route details are not needed.
Full Route + Default Route Receives both full BGP routes and a default route.
Gives routing flexibility, allowing fallback to default when needed.
2. Advertise ASN or AS-SET for Outbound Routing
Choose the ASNs or AS-SETs that you want to advertise to upstream peers. This determines which prefixes can be routed back to your network.
