Appl. No.:

10/645459

Inventors:

Manish Rathi - San Jose CA, US
Rajesh Sharma - Santa Clara CA, US

Assignee:

Extreme Networks, Inc. - Santa Clara CA

International Classification:

G06F 21/00
G06F 7/04
H04N 7/167

US Classification:

713182, 726 26, 725 31

Abstract:

A method and system for auto discovery of authenticator for network login is described. The system includes an authenticator discovery controller of a packet forwarding device that helps a user discover the IP address of the packet forwarding device and directs the user to a network login page. The method includes intercepting a request for a web page from a user who is connected to a packet forwarding device that prevents the user from accessing a network, directing the user to a network login page, authenticating the user, and allowing the user to access the network when the user is authenticated.

International Classification:

H04L 12/56

US Classification:

370390

Abstract:

In an example embodiment, a method at a first routing device is provided. In this method, the first routing device receives an interest for multicast traffic that is transmitted downstream along a point-to-multipoint path in a multicast virtual private network. This interest identifies a source address and/or a multicast group address. Upon receipt of the interest, the first routing device identifies a second routing device, which is upstream to the first routing device, based on the source address and/or the multicast group address. On condition of receipt of the interest, the first routing device creates a bidirectional path between itself and the second routing device.

International Classification:

H04L 12/715
H04L 12/46

Abstract:

This disclosure describes techniques for enabling interoperability between asymmetric and symmetric Integrated Routing and Bridging (IRB) modes. An interfacing component may be configured to receive a first route advertisement from a first edge node in a Layer-2 (L2) fabric. The first route advertisement may correspond to an asymmetric format route, for instance. The interfacing component may be further configured to receive a second route advertisement from a second edge node in a L2/Layer-3 (L3) fabric. The second edge node may be configured for symmetric integrated routing and bridging (IRB). The interfacing component may be configured to re-originate the first route and the second route such that the interfacing component is included as a hop in the resultant routes between the L2 fabric and the L2/L3 fabric.

International Classification:

H04L 12/741
H04L 12/713

Abstract:

A first network device advertises routes of locally connected routes/subnetworks based on the connectivity of the host with respect to peer network devices. The first network device establishes a virtual port channel associated with a virtual network address. The virtual port channel includes the first network device associated with a first network address and a second network device associated with a second network address. The first network device detects that a host is connected to the first network device and determines a next hop address to associate with the host. The next hop address is determined based on whether the host is also connected to the second network device of the virtual port channel. The first network device generates a route advertisement associating the next hop address with the host.

International Classification:

H04L 12/753
H04L 29/06

Abstract:

Methods for assisting data forwarding during convergence in a multi-homed network are disclosed. In one aspect, a first leaf node is configured to detect when a second leaf node advertises a set of Ethernet segments which are local to the first leaf and advertise reachability information for the second leaf, indicating itself as a backup for the second leaf during convergence. A spine node that receives advertisement messages from such first and second leaf nodes programs its routing table to indicate the direct route to the second leaf as the primary path and the route to the second leaf via the first leaf as a backup path to forward encapsulated packets destined to the second leaf. Upon failure of the second leaf, when the spine node receives data packets destined to the second leaf, the spine node sends the packets to the first leaf instead of the second leaf.
