So, speaking about the actual linux mechanisms (not about good practices), it means that if I put an interface under a bridge, it is no longer considered by the kernel as a L2/L3 adressable interface ? right ? As nothing prevents from assigning it a MAC/IP, it's confusing.Jocelyn delalande– Jocelyn delalande2013-10-28 09:37:41 +00:00Commented Oct 28, 2013 at 9:37

1@Jocelyn The other way around. If it is still addressable as L2/3 it will block the other traffic. So it should not be addressed directly if on a bridge.Nils– Nils2013-10-29 20:26:44 +00:00Commented Oct 29, 2013 at 20:26

ok, but by default the port remains adressable on L2 (keeps a MACaddr if I don't remove it), right ? why does it let the L2 traffic flow to the bridge ?Jocelyn delalande– Jocelyn delalande2013-10-30 09:36:52 +00:00Commented Oct 30, 2013 at 9:36

2@Jocelyn As long as it does not respond to arp-requests everything will be good on l2/3. If it does not capture packets it will let pass packets into the network part of the kernel.Nils– Nils2013-11-02 20:10:57 +00:00Commented Nov 2, 2013 at 20:10

Ok. I asked cause I noticed that some trafic was dropped when assigning an address to the port ; but it was caused by rp_filter.Jocelyn delalande– Jocelyn delalande2013-11-04 13:31:18 +00:00Commented Nov 4, 2013 at 13:31

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
