What is SPB protocol?

Shortest Path Bridging (SPB), specified in the IEEE 802.1aq standard, is a computer networking technology intended to simplify the creation and configuration of networks, while enabling multipath routing. It is the replacement for the older spanning tree protocols: IEEE 802.1D, IEEE 802.1w, IEEE 802.1s.

Does Cisco support SPB?

Cisco has no plans to support SPB, said Francois Tallet, Nexus 7000 product manager.

What are 802.1 standards?

IEEE 802.1 handles the architecture, security, management and internetworking of local area networks (LAN), metropolitan area networks (MAN) and wide area area networks (WAN) standardized by IEEE 802. The following are key IEEE 802.1 tasks: Designs and implements standards that regulate network management practices.

Does Cisco support Shortest Path Bridging?

Shortest Path Bridging is now an IEEE draft (802.1aq) that will eventually be included in the 802.1Q standard. Several networking companies, including Avaya, Alcatel, Hauwei and Cisco, are participating in the IEEE SPB initiative and have announced support for Shortest Path Bridging technology.

What is extreme fabric connect?

A standards-based fabric technology based on enhanced IEEE 802.1aq Shortest Path Bridging and IETF 6329, Extreme Fabric Connect combines decades of experience with Ethernet and Intermediate System-to-Intermediate System (IS-IS) to deliver a next generation technology that combines the best of Ethernet with the best of …

What is trill and SPB?

There are two competing protocols here: TRILL (TRansparent Interconnection of Lots of Links) and SPB (Shortest-Path Bridging). TRILL is documented in [RP04] and RFC 6325 [https://tools.ietf.org/html/rfc6325.html] and companions, while SPB is standardized by IEEE 802.1aq [en.Wikipedia.org/wiki/IEEE_802.1aq].

What is the maximum number of SPB nodes allowed?

When designing multi-area networks, it is recommended that you limit the number of IS-IS nodes per area to 500. All traffic to a connected area is destined to the virtual node representing the connected area.

What is 802.1 Q used for?

802.1Q tunneling enables service providers to use a single VLAN to support customers who have multiple VLANs, while preserving customer VLAN IDs and keeping traffic in different customer VLANs segregated. A port configured to support 802.1Q tunneling is called a tunnel port.

What is 802.11 b standard offering in terms of security?

IEEE 802.11 standard security aspects IEEE 802.11 provides security through encryption and authentication. Authentication can be done through an “open system” or “shared key” in either ad hoc mode or infrastructure mode.

What is a fabric connect?

Fabric Connect, in computer networking usage, is the name used by Extreme Networks to market an extended implementation of the IEEE 802.1aq and IEEE 802.1ah-2008 standards. The Fabric Connect technology was originally developed by the Enterprise Solutions R&D department within Nortel Networks.

What are the security benefits of a fabric Connect network?

Stealth Networking Capabilities With Fabric Connect, forwarding is based on ethernet-switched paths, so network topology is invisible from an IP perspective. Since there are no inherent hop-by-hop IP paths, the network topology can’t be traced using common IP scanning tools.

What is Service ID (ISID) in 802 1aq?

Instead, 802.1aq allows assignment of a Service ID (ISID) to a VLAN ID (VID) at the edge of the network. A VID will correspond to exactly one of the possible sets of shortest path nodes in the network and will never stray from that routing.

What is the IEEE Std 802 1q-2011?

This amendment to IEEE Std 802.1Q-2011 specifies shortest path bridging of unicast and multicast frames, including protocols to calculate multiple active topologies that can share learned station information, and support of a virtual local area network (VLAN) by multiple, per topology VLAN identifiers (VIDs).

How does 802 1aq spread traffic on a hop by hop basis?

802.1aq does not spread traffic on a hop by hop basis. Instead, 802.1aq allows assignment of a Service ID (ISID) to a VLAN ID (VID) at the edge of the network. A VID will correspond to exactly one of the possible sets of shortest path nodes in the network and will never stray from that routing.

What does IEEE 802 stand for?
