Abstract
A device receives border gateway protocol (BGP) data associated with links provided in a segment routing network. The segment routing network includes a first autonomous system (AS) with first network devices interconnected by a first portion of the links, a second AS with second network devices interconnected by a second portion of the links, and an inter-AS link provided between one of the first network devices and one of the second network devices. The device filters prefixes of the BGP data to identify BGP data associated with the inter-AS link, where the BGP data associated with the inter-AS link includes data identifying state information associated with the inter-AS link. The device determines an operational state of the inter-AS link based on the BGP data associated with the inter-AS link, and performs one or more actions based on the operational state of the inter-AS link.
