Re: Questions from @gemmellr
- This probably merits additional documentation. When there are multiple
link-route destinations that match the same patterns, link attaches are
balanced across the destinations. Multiple destinations with the same address
share the link load.
- It would be desirable to have policy hooks to allow/disallow this
feature. More importantly, existing produce/consume rights should be enforced
based on allowed addresses. The complexity is the wildcard patterns. We don't
currently have a way to determine if a pattern is allowed. We can only do this
with individual addresses. One solution is to enforce access at link-attach
time when the specific address is known. Another is to implement some form of
pattern validation. The former is not good because it might cause links to be
dropped by one destination when they could have been accepted by another.
