Release Overview

  • New BGP command (neighbor PEER soo) to configure SoO to prevent routing loops and suboptimal routing on dual-homed sites.

  • Implement Route Leak Prevention and Detection Using Roles in UPDATE and OPEN Messages rfc9234
  • BMP L3VPN support
  • PIMv6 support
  • MLD support
  • New command to enable using reserved IPv4 ranges as normal addresses for BGP next-hops, interface addresses, etc.
  • As usual, lots of bugs and memory leaks were fixed \m/
