96 System Administration
a. IPv6 Addr: 2001:428:4C05:87:2121:2222:2323:2424
b. Prefix Length: 64
c. Gateway: 2001:428:4c05:87::1 (the subscriber port address). This may need to be
configured as a default route (ipv6 route ::/0 2001:428:4c05:87::1)
d. DNS: 2001:4860:4860::8888 (The exact address does not matter since the WAN port’s
DNS setting will be used.)
5. Enable the feature under access control and set up allowed external access addresses.
6. Set up any required routing on the host network.
a. Unlike IPv4, under IPv6 we act as a router between the subscriber and network sides. At
the present time the NSE does not support routing protocols, so it’s up to the host network
to route subscriber IPv6 traffic back to the NSE’s WAN port.
b. In our example we have delegated 2001:428:4C05:80:: /60 to the NSE’s subscriber sides,
and the NSE will use whichever it needs of those 16 addresses for the subscriber ports.
c. The ROUTE only needs to tell the network router that all traffic for 2001:428:4C05:80:: /60
should be sent to our WAN port IPv6 address. Depending on the network you might need
to add a similar IPv6 route to a host computer on the WAN network for the same purpose.
Link Aggregation
Link Aggregation provides improved throughput and link redundancy and does not require load balancing to
do it. Aggregation combines two or more physical links into a single virtual link. However, since
“conversations” must be transmitted on the same physical link, all the traffic from a subscriber will travel on
the same link. Loss/restoration of a physical link is detected and traffic is rerouted.
•
Two Link Aggregation Groups (LAGs) are available, and can be used for WAN or Sub connections
as desired. Nomadix LAGs support LACP (Link Aggregation Control Protocol), so when
configuring the connecting switch you would choose “active” mode. LAGs are listed in the Ethernet
Ports / WAN listing like any other port.
•
Individual ports are set to AGG (Aggregated) mode and assigned to one of the two LAGs.
•
The LAG is then set to either WAN or SUB (or OOS).
