Subject: SRv6 Network Programming - ICMP Source Address Selection

Authors,

When an SRv6 node sends an ICMP message, how does it select the ICMP message's source address?

Section 2.2 of RFC 4443 offers two options. If you think that a SID is a unicast address, the first option is applicable. If you think that a SID is not a unicast address, the second option is applicable.

                                                                     Ron

Ron,

As you pointed out in your email, RFC4443 Section 2.2 is very clear about how to select the source address.
draft-ietf-spring-srv6-network-programming does not change this.

Thanks,
Pablo.

Pablo,

Which did you choose?
