*I do not support this draft in the current form. * This document instead of improving the original specification makes it actually worse.
Point 1 - Original RFC sec. 6.2: o Network Address of Next Hop = IPv6 address of Next Hop Proposed text: o Network Address of Next Hop = VPN-IPv6 address of Next Hop whose RD is set to zero As it has been explained when you negotiate in capability AFI2 as next hop it is just 16 octets - not 24. Next hop never has an RD. The fact that some implementations are matching length of NLRI with length of next hop no where should be made equal that next hop has 8 octet dummy Route Distinguisher. If revision is to be made would be to explicitly negotiate capability to infer next hop encoding from the length. Point 2 - Addition of section 6.3 and SAFI 129 is fine, but again next hop encoding is lightly stating suboptimal. Conclusion: As we have discussed on and off line if revision is to be made let's make it both backwards compatible, Let's make it applicable to both IPv4 and IPv6 next hop addresses and let's allow explicit capability where implementations could indicate that it can recognize next hop value from its length. After all we are talking about just 4 discrete possible values here. Cheers, Robert.
