A stub multi-homing solution for IPv6 networks

摘要

Multi-homing is one of the primary causes for the exponential growth rate of the global routing table (GRT). This work proposes a stub multihoming solution called Multi-Addressing with Stub Tunnels (MAST). By combining IPv6 multi-addressing with backup tunnels between a stub and each of its providers, stubs can enjoy the reliability advantages of multihoming without adding to the size of the GRT. An analysis of the current Internet BGP RIBs was conducted. It showed that the current global routing table size of 450K prefix entries would be reduced to about 24K entries if the MAST solution was adopted by all stubs.
