Routing Protocols

  • Nonstop active routing (NSR) support with BGP RIP sharding and BGP UpdateIO features (ACX5048, ACX5096, ACX5448, MX240, MX960, MX2008, MX10016, and PTX5000)—Starting in Junos OS Release 22.2R1, we've enabled nonstop routing (NSR) for BGP RIP sharding and BGP UpdateIO features. With NSR enabled, the backup Routing Engine and backup routing protocol process (rpd) become the primary Routing Engine without negatively affecting the BGP peering sessions with the neighbors if the primary Routing Engine fails. The backup rpd processes the replicated BGP control-plane information and populates the route state in the same multithreaded manner as in the primary rpd.

    After you configure NSR, the show bgp neighbor and show bgp summary commands display the information about the specific shards in the backup Routing Engine. To display the replicated information for a specific shard in the show bgp replication command, use the rib-sharding shard-name option.

    See [show bgp neighbor, show bgp summary, show bgp replication, and BGP Overview.]

  • Support for BGP flow specification (ACX5448, ACX5448-M, and ACX5448-D)—Starting in Junos OS Release 22.2R1, ACX5448 routers support BGP flow specification (BGP flowspec) filters based on the match conditions and actions. BGP flow specification filters support ingress IPv4 and IPv6 addresses. BGP flow specification filters internally creates implicit forwarding table filters or FTFs to mitigate DDoS attacks quickly. The BGP flow specification filters created in hardware have more precedence compared to the interface family inet and inet6 filters (IFF and FTFs).
