Hi, i have done anycast DNS in the past with BIND and had no problems concerning source address selection for replies or queries. Now i am trying to set this up with unbound and i fail to see how to get the source address selection to work correctly.
The anycast address is configured on lo:1 (linux) and get redistributed with RIP. Now unbound replys on queries to the anycast address but with the interface address of the ethernet interface. I would have thought it always takes the queries destination address as the replys source address and only leaves the source address selection to the kernel when sending out queries itself. I have seen "outgoing-interface" but thats the side which works e.g. sending out queries. I'd like unbound to be able to reply to all addresses e.g. the ethernet address aswell so one can monitor liveness from remote which is not possible on the anycast address for obvious reasons.
