7368 ISAM ONT G-240W-C Product Guide
4.2.7
The BRG receives IP addresses for the WAN interface using DHCP or PPPoE. The
BRG can use either Ipv4 or Ipv6 addresses. BRG uses OpenFlow protocol version
1.3.1 to manage Access Control List entries and routing protocols. TR-069 can be
used to manage the local DHCP server and the soft GRE tunnel.
The BRG supports the encapsulation of Ethernet frames from different bridges in the
GRE tunnel to the access tunnel. Multiple bridges can map to the same GRE tunnel.
Where encapsulated packets exceed the MTU (packet size), fragmentation is also
supported.
Upstream QoS can reserve bandwidth for public and private Wi-Fi bridges, based on
profiles defined for the access uplink speed. A unique VLAN tag can be configured
for each SSID on the BRG. Unicast QoS adjustment can be enabled to support
Multicast IPTV
Liveness detection and redundancy, link failure notification, and DHCP local server
fallback are provided to help manage potential problems with gateway access. Event
notification via TR-069 reports when the PON link is up and the tunnel is
unreachable.
4.2.8
This section describes the support for soft GRE tunnels for integration with the 7750
Service Router WLAN gateway. The Nokia 7750 Service Router WLAN GW can
accept soft GRE tunnels from any IP Source Address, in a preconfigured Subnet or
Access Control List, or MPLS label.
4.2.8.1
Generic Routing Encapsulation (GRE) is a tunneling protocol that can encapsulate a
wide variety of network layer protocols inside virtual point-to-point links over an
Internet Protocol network. GRE provides a secure path for transporting packets
through a public network. In essence, GRE creates a private P2P connection, similar
to a VPN, between clients and servers. GRE is the preferred transport mechanism
between the Carrier Wi-Fi access network and the WLAN GW.
GRE works by encapsulating a payload (an inner packet that needs to be delivered
to a destination network) inside an outer IP packet. GRE tunnel endpoints send
payloads through GRE tunnels by routing encapsulated packets through intervening
IP networks. The inner packets are not parsed along the way; only the outer IP
packets are parsed as they are forwarded towards the GRE tunnel endpoint, where
the GRE encapsulation is removed, and the payload is forwarded to its final
destination.
