TNSR (22.06) as a multi-domain MAP-T BR
-
Greetings, all. We're working with NG support on the same, but I thought I'd throw this out of the community.
We're employing TNSR as the Border Relay in a dev MAP-T environment. Each MAP domain represents an edge router (Cable-CMTS, PON-OLT, etc.) We'd like to be able to use one (or a very small number of) DMRs (the synthetic IPv6 /64 to which customer edge devices send their translated IPv4 traffic).
Currently, we can define multiple MAP domains with the same DMR and no errors are thrown, however only the last domain listed in the CLI appears to function properly (others are rejected with ICMPv6:
We believe the math involved should allow for this, but are unsure if there's a gap in the underlying VPP code to account for it, or possibly just a missed use case in the Clixon UI. Any pointers on where to dig into the logic on this (in VPP, Clixon, or both)?

@dgeist there is a bug on TNSR that prevents to learn neighbor mac while you have map enabled on the interface. The workaround is to configure static neighbor entry.
