I understand there are tricks for faster thoroughput on IPv4 with regards to multiple interfaces (network cards) and a single IP address. Say, two 100mbit cards plugged into the same 100mbit switch. Is this `trick' available with IPv6 in any fashion? -- Todd Fries .. [EMAIL PROTECTED]

There are a few ways to accomplish this. If all the | interfaces are on the same lan, then you could have a "primary" and a | "backup" interface. If the interfaces are on different lans, you can run | a dynamic routing protocol and advertise the address as being reachable | through each physical interface on a node. In this case, the address | isn't really configured on the multiple interfaces per-se (you instead | have a "virtual" interface which is assigned the IP address), but the | result is any interface on the node may be used. There are other methods | which may be used as well. | | > If so is there any specific purpose for doing that ?? | | Redundancy. If one interface goes down, traffic will automatically switch | to the another interface without disrupting existing connections. | | > What about link-local address, how would it be used, if single link | local | > address is configured on multiple interface of a same node. | | I'm not sure it is particularly useful. Link-local addresses are really | intended to be used for bootstraping, configuration discovery, route table | maintenance, and the like. Most, if not all, of these protocols work on a | per-interface basis. I suppose it could allow an interface to act as a | "hot standby" for another interface, automatically switching over if the | primary interface fails. But this would only work if the interfaces are | on the same physical lan. If they are on different lans, then the two | interfaces are in different link-local scope zones and are treated as | unique addresses. | | Roy | -------------------------------------------------------------------- | IETF IPng Working Group Mailing List | IPng Home Page: http://playground.sun.com/ipng | FTP archive: ftp://playground.sun.com/pub/ipng | Direct all administrative requests to [EMAIL PROTECTED] | -------------------------------------------------------------------- -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
