摘要： A technique restores adjacencies between a non-stop forwarding (NSF) router and its neighboring routers during reload of routing protocol software on the NSF router within a computer network. When a new instance of the routing protocol software is re-loaded, each interface of the NSF router is placed in a special state that enables it to receive incoming Hello packets from its neighboring routers. When placed in the special state, the interface passively “listens” for incoming Hello packets from the neighbors to determine which neighbors send the packets. The router thereafter promptly creates and sends a unicast Hello packet to each neighbor from whom it has received an incoming Hello packet and creates associated neighbor data structures.

摘要： In a repeater having multiple ports and receiving at a source port a data packet containing a received address, an address mapping system including a content addressable memory (CAM) with address registers containing stored addresses, and an address mapping matrix coupled to said CAM, for perfectly mapping any of the address registers to any of the ports. According to one aspect of the invention, it operates in a repeater having an address compare and disrupt security system. The preferred embodiment of the present invention includes a content addressable memory having address registers containing stored individual and multicast addresses associated with each repeater port, and an address mapping matrix including a disrupt enable circuit associated with each port, for enabling the disruption of the data packet at that port when the received destination address does not match the associated stored addresses, and for disabling the disruption of the data packet at that port when the received destination address matches the stored address in a particular register and that particular register is mapped to that port via an address mapping register.
