NETGEAR 8800 User Manual R (Continued) root port route aggregation route flapping route reflector routing confederation RSTP S SA SCP sFlow SFP 6in4 tunnels In STP, the root port provides the shortest path to the root bridge. All bridges except the root bridge contain one root port. In BGP, you can combine the characteristics of several routes so they are advertised as a single route, which reduces the size of the routing tables. A route is flapping when it is repeatedly available, then unavailable, then available, then unavailable. In the XCM8800 BGP implementation, you can minimize the route flapping using the route flap dampening feature. In BGP, you can configure the routers within an AS such that a single router serves as a central routing point for the entire AS. In BGP, you can configure a fully meshed AS into several sub-ASs and group these sub-ASs into a routing confederation. Routing confederations help with the scalability of BGP. Rapid Spanning Tree Protocol. RSTP, described in IEEE 802.1w, is an enhanced version of STP that provides faster convergence. The NETGEAR implementation of RSTP allows seamless interoperability with legacy STP. Source address. The SA is the IP or MAC address of the device issuing the packet. Secure Copy Protocol. SCP2, part of SSH2, is used to transfer configuration and policy files. sFlow allows you to monitor network traffic by statistically sampling the network packets and periodically gathering the statistics. The sFlow monitoring system consists of an sFlow agent (embedded in a switch, router, or stand-alone probe) and an external central data collector, or sFlow analyzer. Small form-factor pluggable. SFP is a specific type of GBIC, designed for use with small form factor connectors. These transceivers offer high speed and physical compactness. The 6in4 tunnels, which encapsulate IPv6 packets into IPv4 packets, use dynamic routing protocols to establish connectivity between several IPv6 networks through over the intervening IPv4 network. The 6in4 tunnel must be created at each tunnel endpoint. The IPv6 routing protocol considers the 6in4 tunnel as a single IPv6 hop, even if the tunnel comprises many IPv4 hops; the IPv6 protocol considers the 6in4 tunnel as a normal IPv6 point-to-point link. You can have many 6in4 tunnels per VR. 940 | Appendix E. Glossary
