Below is the list of IPv6 features currently supported in ExtremeXOS 15.7.
First Hop Redundancy Protocol (FHRP):
- Neighbor Discovery (ND)
- Path Maximum Transmission Unit Discovery (PMTUD)
- DHCPv6 Relay and Client
- Static Routing
- 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
- Telnet and SSH
- TFTP and SCP
- Ping and Traceroute
- sFlow IPv6 Sampling
- NTP and SNTP
- DNS Client
* 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.
Hardware Table Capacity:
- /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
- 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
- /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.
- X460 - 3K, X670 - 3K, BD8K c-Series - 3K, BD8K xl-Series - up to 8K, BDX8 a-Series - 3K, BDX8 xl-Series - up to 49K
- Hardware Neighbor (ARP) Table:
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
