Ipv6 Multicast; Ssh Over An Ipv6 Transport - Dell Force10 C150 Configuration Manual

FTOS IPv6 supports quality of service based on DSCP field. You can configure FTOS to honor the DSCP
value on incoming routed traffic and forward the packets with the same value.
Refer to Chapter 41, Quality of Service
packets in the QoS chapter for information relating to the

IPv6 Multicast

IPv6 Multicast is supported on platforms:
FTOS supports the following protocols to implement IPv6 multicast routing:
• Multicast Listener Discovery Protocol (MLD). MLD on a multicast router sends out periodic general
MLD queries that the switch forwards through all ports in the VLAN. There are two versions of MLD:
MLD version 1 is based on version 2 of the Internet Group Management Protocol (IGMP) for IPv4,
and MLD version 2 is based on version 3 of the IGMP for IPv4. IPv6 multicast for FTOS supports
versions 1 and 2
• PIM-SM. Protocol-Independent Multicast-Sparse Mode (PIM-SM) is a multicast protocol in which
multicast receivers explicitly join to receive multicast traffic. The protocol uses a router as the root or
Rendezvous Point (RP) of the share tree distribution tree to distribute multicast traffic to a multicast
group. Messages to join the multicast group (Join messages) are sent towards the RP and data is sent
from senders to the RP so receivers can discover who are the senders and begin receiving traffic
destined to the multicast group.
• PIM in Source Specific Multicast (PIM-SSM). PIM-SSM protocol is based on the source specific
model for forwarding Multicast traffic across multiple domains on the Internet. It is restricted to
shortest path trees (SPTs) to specific sources described by hosts using MLD. PIM-SSM is essentially a
subset of PIM-SM protocol, which has the capability to join SPTs. The only difference being register
states and shared tree states for Multicast groups in SSM range are not maintained. End-hosts use
MLD to register their interest in a particular source-group (S,G) pair. PIM-SSM protocol interacts with
MLD to construct the multicast forwarding tree rooted at the source S.

Independent Multicast (IPv6) for configuration details.

SSH over an IPv6 Transport

IPv6 SSH is supported on platforms
FTOS supports both inbound and outbound SSH sessions using IPv6 addressing. Inbound SSH supports
accessing the system through the management interface as well as through a physical Layer 3 interface.
