Anycast IP Gateway for active-active routing with shortest path forwarding. Client visibility
is improved with Node Alias for end-system discovery and DHCP Fingerprinting for device
identification. Fabric enhancements include Flex UNI interface improvements and support for
IS-IS external route preferences with tagging for external routes to prevent redistribution
loops. ExtremeCloud SD-WAN integration adds Local Breakout for internet-destined traffic and
VRF support across all models. Security updates include OCSP support for RADSec certificates,
with added management options for SSH, SCP, and SFTP sessions. Additional improvements include
dynamic ACL actions, extended MLT name lengths, and enhanced rate limiting for unknown unicast
