Correct. It also means that they can inject some routing information - -- i.e. that the ip address configured onto their loopback interface is reachable through the ip address on their ethernet interface subject to a certain cost. The intent is to provide an efficient failover mechanism (one host crashes, a backup host is automatically used since they both have the same address on their loopbacks, but the backup is advertising it with a higher cost), as well as the ability to easily relocate services to different machines and load balance in a way that doesn't break if one host goes away (à la DNS round-robin) or cost a fortune (à la local-director). - -w - -- Will Waites \________ [email protected]\____________________________ Idiosyntactix Ministry of Research and Development\ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.1 (OpenBSD) Comment: Processed by Mailcrypt 3.5.5 and Gnu Privacy Guard <http://www.gnupg.org/> iQEXAwUBOSQl5g4cK24IcAwYFAOpywP/SjUKo09WCeBW0Wjq+6znsYJ6Eh7+Tirh Ik7To9fFie00kmpc4VSYitKFpQEBNX7qN9y0vtdq0B5hzzUbUeDqip+xM3gdPO5G VV2wSdob84S59eruRl6zqU7+WrcCqW5kq5OG9e3U1sG/5b38jcJbFB8KgvXwthgO I8aZhsEK6YkD/RRZNEtkLbwHvBdMXI4SpxVIY5rjWCIbmgriGHzenJ9NVOXufgqv KeJ8617eFcgSOCZUMtopoT2Q+Iorzm1nVGLHNdI8F/vTutV0RDgSGKjhOqx9yK69 aoVLsuqzr8qVQolzNh3ZPOZh2a2YkvpgtMDVK5fsSxrqNc37/4C4aYBl =6Zzr -----END PGP SIGNATURE-----
