Abstract: Embodiments described herein achieve proxy FHRP for anycast routing services through the coordination of L2MP edge switches to allow load balancing for the use of routing services. Such embodiments may avoid duplicity and coordinate control planes between the edge switches to present a proxy interface to the rest of the network for the routing services. As such, multipathing and load-balancing for efficient use of crucial services may be provided for client nodes inside the network.

Abstract: In an embodiment, a method comprises: detecting a change in a multiple-switch configuration in a data communications network comprising a plurality of packet data switches configured as roots of multicast trees. In response to detecting that the multiple-switch configuration has changed, a first value, a second value and a third value representing limits on a number of multicast trees supported in the network and prioritization of the switches are retrieved. The method further comprises determining a type of the multiple-switch configuration change. In response to determining that the type indicates that a first switch was added to the multiple-switch configuration, using at least the first, second and third values, it is determined whether to configure the first switch as a first root in the multiple-switch configuration. The method is performed by one or more computing devices.

Abstract: Methods and apparatus for segregating traffic are disclosed. In accordance with one embodiment, a traffic splitter identifies a set of links coupled to the traffic splitter, where the set of links includes two or more uplinks, wherein each of the two or more uplinks are implemented in a common physical media. The two or more uplinks include a LAN uplink coupled to a LAN and a SAN uplink coupled to a SAN. The traffic splitter prevents SAN traffic from reaching the LAN via the LAN uplink. In addition, the traffic splitter prevents LAN traffic from reaching the SAN via the SAN uplink.
