Hello all, I've been scratching my head and banging it against a brick wall for the last month, trying to get this sorted out. In our office, we are announcing a /48 v6 prefix to AAPT from our BGP router. We then have a NAT router for our internal VLANs. We wish to assign addresses to clients within our office. If I set static addresses all works ok so I know it's not a routing issue. We have 4 VLANs within our office to which we wish to allocate a /59 to each. Would anyone have any examples of configs or be able to point me in the right direction, to have our NAT router announce IP addresses to our clients? Thanks, CH.
Hi, No idea if this is the "Right" way to do it, but has been working for me for 12months or so now.
