TitleThe list of IPv6 features currently supported in ExtremeXOS
What features of IPv6 are currently supported in ExtremeXOS?
  • EXOS All
Below is the list of IPv6 features currently supported in ExtremeXOS 15.7.

Fundamental Feature:
  • Neighbor Discovery (ND)
  • Path Maximum Transmission Unit Discovery (PMTUD)
  • DHCPv6 Relay and Client
First Hop Redundancy Protocol (FHRP):
  • VRRPv3
Routing Protocol:
  • Static Routing
  • RIPng
  • OSPFv3 - only supports Stub Area and Totally Stubby Area.
  • ISIS for IPv6
  • Multi-protocol BGP (MBGP) for IPv6
  • Bidirectional Forwarding Detection (BFD) - only supports Static Routing and OSPFv3
  • Routing Policy
  • Equal Cost Multi-Path (ECMP) - up to 64
  • 6to4
  • IPv6 in IPv4
  • Telnet and SSH
  • TFTP and SCP
  • SNMP
  • Ping and Traceroute
  • sFlow IPv6 Sampling
  • NTP and SNTP
  • DNS Client
  • Protocol Independant Multicast (PIM) - Sparse Mode (SM), Dense Mode (DM) and Source-Specific Multicast (SSM)
  • Multicast Listener Discovery v1 (MLDv1)
  • Multicast Listener Discovery v2 (MLDv2)
  • Multicast Listener Discovery - Source-Specific Multicast (MLD-SSM) 
  • Multicast Listener Discovery (MLD) Snooping
  • ACL
           * Since current hardware ACL entry is 181 bit long, it's recommended to use "ACL double width" to have both destination and source IPv6 addresses in an ACL entry.
  • ACL Network Zone
Hardware Table Capacity:
  • Hardware Routing Table:
            - /64 or smaller subnet mask routing entries: X460 - 6K, X670 - 8K, BD8K c-Series - 6K, BD8K xl-Series - up to 240K, BDX8 a-Series - 8K, BDX8 xl-Series - up to 512K
            - /65 or bigger (~/128) subnet mask routing entries: X460 - 256, X670 - 256, BD8K c-Series - 256, BD8K xl-Series - up to 240K, BDX8 a-Series - 256, BDX8 xl-Series - up to 512K
            * Since the internal hardware IPv6 routing entry is 64 bit long, it's recommended to assign /64 or smaller subnet mask IPv6 addresses to point-to-point routing interfaces between network devices.
  • Hardware Neighbor (ARP) Table:  
            - X460 - 3K, X670 - 3K, BD8K c-Series - 3K, BD8K xl-Series - up to 8K, BDX8 a-Series - 3K, BDX8 xl-Series - up to 49K

Below is the list of IPv6 features that are supported in ExtremeXOS 16.1 and 21.1.
  • Bidirectional Forwarding Detection (BFD) for IPv6 BGP (MBGP)
  • RADIUS Client for IPv6
  • Syslog Client for IPv6
  • Not-so-stubby Area (NSSA) in OSPFv3
Additional notes
The following is NOT supported in ExtremeXOS at present.
  • 6PE (VPN-IPv6 in MBGP)
  • Authentication in VRRPv3 
  • IPv6 address for sFlow agent and collector
  • DHCPv6 Server
  • TACACS+ Client for IPv6
  • Default Route Origination in OSPFv3
