Abstract: Remediation of network devices that are failing is accomplished using a Shared Failure Domain (SFD) database that provides neighboring device/link information to remediation tools. SFD refers to a group of objects (links/devices) that share a same failure model. A state change of one or multiple of the objects results in a corresponding action on other devices linked together through the SFD. Moreover, the SFD data is available in a central repository and software tools consult the central repository for failure domain data before taking remedial actions. SFD data is generated using configuration generation and device state. Software tools lookup SFD data during operational events (device/link down) and take appropriate actions on the neighboring devices.

Abstract: Technologies are provided for managing routing updates within computer networks using brick identifier (ID) values. For example, brick ID values can be assigned to bricks of routers within a network. When a router of the network receives a routing update, the router can check the brick ID value of the routing update and compare it to its assigned brick ID value. If the brick ID values match, then the router can process the routing update using a preferred procedure. If the brick ID values do not match, then the router can process the routing update using a standard procedure. The preferred procedure can result in faster convergence of routing changes within the network.
