I am trying to add IPV6 to and existing network. The network has 2 MX64 in hot standby. Q1: Is Hot standby supported in IPv6 ? (does not seem to be support for static shared address) (my current static route points to primary [see picture]) Because in hot standby I need to use 1 subnet of /64 on the outside between MX64 and the rest on the internal vlans (see picture) I have setup static addressing on the WAN and this is working I have setup static addressing on the LAN and this is working. Q2 I do not understand how to get an IPV6 DNS server to the clients on LAN, ipv6 is working buy they are using IPV4 for DNS Where do you set the DNS server they get ?? I added xxxx:yyyy:zzzz:dd/48 to the IPv6 prefixes as I don't have any AUTO vlans (or should I be adding multiple /64 prefixes for every vlan ?? ) In the VLAN Assignments all the VLAN show with the correct Subnet prefix and the status is active IPv6 works. but I then found the next day the VLAN Assignments tables went to expiring soon and then empty and IPv6 was not working.. Q3 Am I doing it totally wrong ???? I configured the Cisco router instead to be a IPV6 dhcp server and setup Prefix pool ipv6 local pool MERAKI_POOL xxxx:yyyyy:zzzz::/40 56 ipv6 dhcp pool MY_V6 prefix-delegation pool MERAKI_POOL dns-server xxxx:yyyy:101::1 dns-server xxxx:yyyy:101::2 domain-name xxx.com.au and then put all all meraki IPv6 settings on auto. both mx64 got IP address xxxx:yyyy:zzzz:ddff:: and the IPv6 prefix got the address from auto it then gave xxxx:yyyy:zzzz:dd01: /dd:02 / dd:03 to each vlan. this worked. But VLan60 had the wrong IPv6 address and the static route required in router to point to pri MX would fail if the MX got a different address. Either I can not find it or the IPv6 configuration for meraki is hard to find. I would love some insight from the IPv6 experts...... Q4) When testing IPv6 some of the testing sites say IPV6 relies on some ICMP IPv6 messages. Is this best practice ??? should I be adding a firewall rule to outside to allow ICMPv6 traffic any to xxxx:yyyy:zzzz:dd:: ??
