Hi WG, Regarding the errata - the errata claims that cause of it is the bug in an implementation, sending DBD with Interface MTU = 0. Maybe it is so, but it seems that real bug is in implementation(s), receiving and dropping such DPD. Both RFCs - 5838 and 5340 - inherit rules for receiving DBD

Hi Acee, Rajesh, RFC 6565 states that the same communities, defined in RFC 4577, are reused. Just before the text, quoted by Rajesh, there is statement: "The BGP Extended Communities attributes defined in [RFC4577] are reused for convenience." RFC 4577 defines sub-type 0x05 and also refers to

[Lsr] Link Data value for Multi-area links

Hi WG, RFC 5185 says that Neighbor's IP address to be encoded into Link Data field. Per RFC 2328 router's own IP address to be encoded into Link Data. What is the reason to advertise neighbor's IP address for multi-area links and not local IP address? It seems like bug. Could someone comment

Hi Anton, I tend to agree with Ketan, but with slightly different proposal. Would not it be simpler to advertise IPv6 Router Address TLV (TLV type 3) by OSPFv2 Opaque LSA (in addition to advertising of Router Address TLV) and to advertise Router Address TLV (TLV type 1) by OSPFv3

assume that some router uses Interface IDs for two-way check, but it is not so straightforward when we have deal with FAs. Acee, two-way check could be disabled on the router that is owner of FA, but how other routers will distinguish regular P2P from FA? Thank you. Best regards, Alexander Okonnikov
