Hi Greg, with two nits: · s/Greg Mersky/Greg Mirsky/ · s/XX, Ericsson/Greg Mirsky, Ericsson/ I agree with the Minutes. Regards, Greg From: BIER [mailto:bier-bounces@ietf.org] On Behalf Of Greg Shepherd Sent: Monday, July 27, 2015 10:57 AM To: bier@ietf.org Subject: [Bier] WG Meeting Notes Please read and respond with approval or corrections. Thanks! Greg ----- Welcome, Notewell, Agenda bash chairs 5 min draft-pfister-bier-mld-00 Pierre Pfister 10 min Pierre presenting Draft is so far only? Draft for dynamically tying BIER to IP multicast flows (flow overlay layer). Targeted for small/averaged sised networks. Shep Q: Do you have a specific use case in mind ? A: Could be applied to homenet. A: Simple not only wrt. scale but also overall solution complexity. BMLD queriers, BMLD Queriers Slide 6: changes required to MLD. Open issues (slide 8): prevent duplicate forwading. Prevent duplicated packet from leaving the network. Q Shep: Ingres/egres forwarder duplication mechanisms are different from each other. Maglianna?/Cisco: Title should imply it applies to IPv4/IPv6. Andrew Doglanv: Looks like extending BIER domain to access side. might be better to enhance BIER itself. draft-ietf-bier-architecture-01 draft-ietf-bier-mpls-encapsulation-01 Ijsbrand Wijnands 15 min Ice presenting Implementations should support in parallel 2 bitstring lengths to allow migration from one to the other. draft-ietf-bier-mvpn-01 Mahesh Sivakumar 10 min Mahesh presenting draft-xu-idr-bier-extensions-02 Xiaohu Xu 10 min Peter from Cisco: BGP draft moved TLV into sub-TLV which is inconsistent in the encoding scheme to the IGP BIER extensions. Please make it consistent in encoding. Ice: Does exactly announce the properties of BIER like the IGP extensions, networks only running BGP will need this. Looks good. Would like to see this adopted. Call for adoption being put onto the list. draft-eckert-bier-te-arch-01 Toerless Eckert 10 min Ice: SI should be changed to sub-domains Greg Mersky: Do you plan TE encap to also be MPLS? Toerless: Any encap will work. Ice: How to route TE from SPF traffic - we announce a different label in the IGP for TE Call for adoption being put onto the list. draft-mirsky-bier-oam-requirements-00 Gregory Mirsky 10 min No questions. Call for adoption will be put to the list. draft-kumarzheng-bier-ping-01 Gregory Mirsky 10 min No questions draft-zzhang-mpls-icmp-bier-01 Jeffrey Zhang 10 min claification question: sam aldrin: TTL exiry - Tunnel Transport Label. Proposed procedure is that instead of dropping packet it would generate signaling. This is generalizing whats done for IPv4/IPv6 packets. XX, Ericsson: BIER packet does not have any IP information. where is ICMP packet sent to: to local host, from there on it is label switched to BFIR. Ice: BFIR is in BIER packet, so should be possible to "send back" packet equally to how it's done in MPLS networks for ICMP of IPv4/IPv6 packets. Greg: not working group item yet. will consider WG adoption call. draft-chh-bier-bier-yang-00 Ran Chen 10 min
