Dynamic Routes (BGP)
In this deployment example, we will configure the Anapaya EDGE to dynamically advertise routes that are reachable.
IP prefixes that are learned from the SCION network are advertised to the LAN via BGP, conversely, IP prefixes that are reachable in the LAN need to be advertised to the EDGE appliances via BGP as well. When an IP prefix is no longer reachable via the SCION network, it is retracted from BGP and the LAN will no longer use that EDGE appliance to reach the SCION network.
Refer to the Getting Started Setup guide for step-by-step instructions on how to interact with the Anapaya appliance.
Information
The configuration examples below are based on the single EDGE setup and need to be adapted to your specific setup.
Additional information provided by the customer
| BGP Router | Router IP | ASN |
|---|---|---|
| EDGE appliance | 10.10.0.12 | 65012 |
| LAN side | 10.10.0.1 | 65001 |
BGP
The following BGP section is added to configure the eBGP session between the EDGE appliance and a BGP router in the internal network.
IP-in-SCION tunneling
The IP-in-SCION tunneling
section needs to be adjusted.
The static_announcements list is no longer required. Instead, the EDGE appliance propagates the IP
prefixes that are received via BGP from the LAN side router to the SCION network. The rest of the
IP-in-SCION tunneling configuration remains the same as in the single EDGE setup
example.
