Network intervention completed successfully
The planned intervention on our main router has been completed successfully.
We replaced the old hardware with a more powerful router and migrated our routing software from Quagga, which is now obsolete, to FRR / FRRouting. This migration required particular care, because FRR applies some BGP configuration rules differently from Quagga.
The effective interruption during the switchover was around 5 minutes.
The new router is now connected to our internal infrastructure through three redundant 10 Gbit/s links, connected to different switches in our new internal switch ring. This architecture improves network resilience in case of a link or switch failure.
BGP sessions were re-established quickly. Our IPv4 ranges are correctly announced, and the router now imports the full Internet routing table, around one million routes.
This migration resolves several routing problems observed recently, caused by the memory limits of the old router in the face of the continued growth of the global BGP table. Initial tests show that the new hardware handles this load without difficulty.
In the coming months, the next steps will be to finally deploy our IPv6 prefix, and then replace the second router in order to rebuild a redundant routing architecture combining iBGP and eBGP.
