Hi Rakesh, thank you for your thoughtful consideration of our discussion. I have a couple of questions to draft-gandhi-spring-twamp-srpm and hope you can clarify if I understand it correctly. In section 4.1 the process of selecting the destination IP address described s follows:
When known, the reflector IPv4 or IPv6 address is used as the destination address. If not known, the address in the range of 127/8 for IPv4 or 0:0:0:0:0:FFFF:7F00/104 for IPv6 is used as destination address. And Figure 2 presents an IP packet with the DM probe query message. I can imagine how the presented IP packet is encapsulated in SR-MPLS. Can you kindly clarify how it works in the case of SRv6? Would it be IP-over-SRv6 encapsulation? And I'm somewhat confused by the condition "if [refletor's IP address] not known". When this case might be used? Also, I've been explained that the proper notation of IPv6 addresses that are IPv4-mapped IPv4 loopback addresses is ::ffff:127.0.0.0/104.
