Questions about multicast replicators
Hi,
I have the following questions about multiclassifier and replicators:
- Multiclassifier and replicators are (S,G) designed, this means:
-- If we have (*,G) entries we need to create several replicators in
place of one.
-- Same if we want support masks, in S and/or G.
- Checking of iif is (S,G) oriented. In the case of protocols without
notion of source, such as CBT, Multiclassifier upcalls WRONG_IIF each
time a packet arrives through an interface different to iif. In this
case, WRONG_IIF must only occurs
if iif not belongs to the set of interfaces asociated with the entry
(parent + children)
Solution?
- Add masks in Multiclassifier entries and forward packets using longest
match prefix?
- Provide different options for iif checking?
Any comment will be appreciated
