Hi,

"draft-ietf-lisp-rfc6833bis-14" section "8.4.1 Anycast Map-Resolver Operation" says

"Note that Map-Server associations with ETRs SHOULD NOT use anycast
addresses, as registrations need to be established between an ETR and
a specific set of Map-Servers, each identified by a specific
registration association."

In my opinion it is sensible to use anycast addresses for map servers of a distributed database for fail-over/load balancing cases and the "SHOULD NOT" is to limiting.

Instead I suggest to encourage operators to specifially consider possible pitfalls of anycast operation.


Regards,


Renne
