Release Overview

New Features Highlight

  • BFD the ability to listen for specific VRFs only
    • Configure which VRFs the BFD daemon will listen to. By default, BFD listens to all VRFs present in the system, including the default VRF. Default VRF must be specified as default.
  • BGP SRv6/MPLS coexistence
    • Allow MPLS and SRv6 to coexist on the same L3VRF, even for a given prefix. This feature is important in brown fields where some operators want to migrate from MPLS to SRv6 backbone.
  • BGP SRv6 locator per VRF support
    • Ability to choose SRv6 locator per VRF.
  • BGP Error handling (RFC 7606) for iBGP peers
    • Before 10.5.0, once we received a malformed packet between iBGP peers, we always reset the session, and with this release, we handle malformed packets the same way as for eBGP (by withdrawing or discarding the malformed packets).
  • BGP IPv6 Link-Local Capability is disabled by default
    • In 10.4.0, this capability was enabled by default for a “datacenter” profile, but it’s disabled for 10.5.0 and will be backported to 10.4.2 as well. The problem arises when the receiver has configured a route-map with set ipv6 next-hop prefer-global and we send only an IPv6 Link-Local address; therefore, it was decided to revert it to be disabled by default.
  • BGP BGPID Next-Hop Characteristic
    • In some cases, the BGP speaker sending a route might encode only a link-local address and no global address. To provide uniqueness in this case, it is sufficient to associate the BGP Identifier and AS Number of the route's sender. The BGP Identifier Characteristic (BGPID) provides a way to convey this information if required.
  • BGP EVPN flooding per VNI support
    • Add an ability to adjust BUM flooding per VNI, instead of just globally. E.g., disable flooding only for an arbitrary VNI.
  • BGP RPKI strict mode
    • RPKI strict mode prevents BGP from establishing a session if no RPKI cache server
      is connected.
  • BGP rejects AS_SET by default
    • Until 10.5.0, it was disabled by default, and since RFC 9774 was published, we switched this on by default (to reject).
  • BGP has lots of improvements for Graceful-Restart
  • PIM/PIMv6 route-map support to allow users to filter IGMP/MLD joins using source/group/ interface combinations
  • Support for multiple SRv6 locators
    • This extends the SRv6 SID Manager to add support for multiple locators.
  • Zebra 16-bit next hop weights support
    • The weights used in ECMP’s consistent hashing have been widened from 8 bits to 16 bits since the 6.12 Linux kernel.
