### AI overview

A configuration guide for using BGP on the Alta Labs Route10, which provides dynamic routing through an FRR-style shell. It covers private ASNs, example prefix advertisement, interface addressing, access to the configuration shell, and session verification.

### Source excerpt

The Alta Labs Route10 includes dynamic routing support through FRRouting (FRR). This article walks through a complete BGP configuration example using private ASNs, a test prefix advertisement, inbound community tagging, and route filtering. It also covers where to access the FRR shell within the Route10 interface and how to verify that the BGP session is operating correctly. The post Example BGP Configuration on the Alta Labs Route10 appeared first on Justin Wilson (j2sw).

### AI overview

The article analyzes a May 20, 2025 BGP incident in which a corrupt BGP Prefix-SID attribute containing zeroed internal data interacted with JunOS and Arista EOS behavior. JunOS propagated the message, while Arista EOS devices reset sessions, causing routing instability and potentially brief connectivity loss for some networks.

### Source excerpt

benjojo reports: At 7AM (UTC) on Tuesday May 20th 2025 a BGP message was propagated that triggered surprising (to many) behaviours with two major BGP implementations that are often used for carrying internet traffic. This caused a large number of "internet facing" BGP sessions to automatically shut down, causing at the very least some routing instability, and at worst brief loss of connectivity for some networks. BGP implementations failing in various ways after seeing something incorrect/unexpected is definitely not a new thing...
