From: BESS <[email protected]<mailto:[email protected]>> on behalf of Anoop Ghanwani <[email protected]<mailto:[email protected]>> Date: Tuesday, July 18, 2017 at 10:39 PM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [bess] a question about bundled service in draft-ietf-bess-evpn-overlay-08
This is what the draft says about bundled service: https://tools.ietf.org/html/draft-ietf-bess-evpn-overlay-08#section-4 >>> 8) When a 802.1Q interface is used between a CE and a PE, each of the VLAN ID (VID) on that interface can be mapped onto a bridge table (for upto 4094 such bridge tables). All these bridge tables may be mapped onto a single MAC-VRF (in case of VLAN-aware bundle service). >>> So it sounds like 1:1 is supported (that's the straightforward case where the inner VLAD ID is stripped from the encap'ed packet) and All:1 is supported (i.e. the service is blind to the incoming tag and just preserves it as is, potentially with normalization if translation is required). What about the case for n:1 where I want some subset of VLAN IDs coming in on a port to map to VNID1, and another subset map to VNID2? Is that explicitly disallowed? If so, why? That's is also supported. Refer to section 6 of RFC 7432 for different service interfaces that are supported. Cheers, Ali Thanks, Anoop
