Release 2.66

Note

This version is broken. ASTF mode does not connect move to v2.71

  • BIRD integration see bird. (first release)

    • Routing protocols support BGP/OSPF/RIP and more on top of IPv6/IPv4 using linux namespace with scale of millions of routes and automation API

    • Change in service mode see service_mode. with --software mode and off mode packets will not forward to Rx.

Note

Breaking change: service mode has 3 states now instead of only off/on:

  1. On - all the packets are forwarded to RX core (as before).

  2. Off - default mode.
    Before v2.66, non-TCP/UDP packets were forwarded to RX core in multi-core software mode (--software).
    After v2.66 (including), in the mode above, those packets are dropped (for more flexibility).

  3. Filter - new mode. In this case, specific packets are forwarded to RX core.
    For example, BGP packets for BIRD. It is relevant only for software mode.
    Using this mode you would be able to run TCP/UDP traffic in high rate while keeping the routing protocols to function.
