[jboss-jira] [JBoss JIRA] (AS7-3041) IPv6: Invalid binding to IPv6 address when zone id identifier is specified

[Brian Stansberry (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/AS7-3041?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12651309#comment-12651309 ] 

Brian Stansberry commented on AS7-3041:
---------------------------------------

An interface binding configuration can include more than one criteria, including <nic name="eth0"/> and a regular-expression based nic-match criteria. So users wishing to avoid ambiguity should use that to make their choice explicit.

We'll look into having the address resolution algorithm fail if more than one possible address matches the criteria.

> AS7 binds incorrectly in several cases when IPv6 address setting includes _zone id_ identifier. For ex. _::1%lo_ produces correct binding at all (_::1:3528_ too), but _fe80::200:ff:fe00:1%p2p1_ (link-local IPv6 address of network interface p2p1) produces binding to _:::3528_ (it's an issue).
> Warning: In multiple homed servers (= server with several physical network interfaces/network cards) it is possible to have more than one network interface with the *same* IPv6 address (compare it to IPv4 world where this case isn't possible) - IPv6 link local address is unique only on link and so the setting needs to include network identifier (network interface name or its index) - every networked AS7 component has to accommodate this setting and produces correct binding.
