All VPC Routers have the BGP session to the first available IPV6 address in the network (Cloud uplink routers) and accepts all networks in the Supernet /50 and are a member of a Private AS (this needs to be configurable in the CS UI to avoid duplicates).


 



IPv6 to IPv4

Any tunnel mechanism can be used to tunnel IPv6 packets. One such example is 6to4. As VPC Router is used as the gateway, we need to enable this on the VPC Router and route all the IPv6 packets using VR's public IP. Example for such configuration is described in below link

HAProxy is able to do the PIv6 to IPv4 proxying.

A basic TCP config:

Code Block
global
    user haproxy
    group haproxy
    daemon
    log /dev/log daemon

defaults
    timeout client 5000
    timeout connect 5000
    timeout server 10000

listen webserver1
    bind 2001:db8:abc:123::cafe:80
    mode tcp
    server webserver1 192.0.2.1:80

Future Enhancement
  • Support for Network ACL to allow ingress/egress traffic for an external network. For this a network administration facility could be introduced in ACS (low pro)
