Hi all,
I’m running a recent build of 1.4 (built post announcement of EPA1) and am learning about IPV6 and trying to split and assign a global unicast /48 (from HE.net) into /64 prefixes for use internally across the various subnets and to get everything talking internally through IPV6.
I’ve assigned one vlan interface (for now) with address 2001:x:x:20:x:x:x:1/64 and setup a DHCPv6 server with start/stop address range within that /64. DHCPv6 assignment is working as the client received addresses from 2001:x:: but I’ve noticed the default router address is a link-local address and not 2001:x:x:20:x:x:x:1/64 which I would have expected.
On the IPV4 side there is the default-router command where you specify the router interface address to use - in my case 10.0.20.1 … how do you achieve the same outcome on the IPV6 side of things. I understand it would be through router adverts but not sure how to configure that differently from what I have done below so that each subnet would get its assigned /64 prefix route ?
Thanks in advance 
set service router-advert interface eth1 prefix 2001:x:x:0:0:0:0:0/48
set service dhcpv6-server shared-network-name vl20_main subnet 2001:x:x::/48 address-range start 2001:x:x:20::100 stop 2001:x:x:20::999
set service dhcpv6-server shared-network-name vl20_main common-options name-server 2001:x:x:255:0:0:0:2
