Software Features
The router has rich features like routing, load-balancing, auto backup, network address
translation, quality of service and remote management satisfying most of the needs of the
SMB market.
Routing
The router supports static, dynamic and policy-based routing.
Static Routing -
The network administrator can manually configure the routes
according to his network topology.
RIP -
The Routing Information Protocol (or RIP) enables the routes to be learnt
dynamically, avoiding cumbersome manual configuration. The router supports
both RIPv1 and RIPv2 versions.
OSPF –
The Open Shortest Path First (OSPF) enables the routes to be learnt
dynamically, avoiding cumbersome manual configuration. OSPF is a link-state
protocol, which is more suitable for large networks.
Policy-Based -
Policy-based routing helps to define custom policies for routing
traffic. For example, policy routes can be defined to route all HTTP traffic
through WAN1 and E-mail traffic through WAN2.
Multicast –
Multicast allows a host to transmit an IP datagram to a set of hosts
that form multicast group. Every member in a multicast group that uses the same
multicast group can receive a copy of the IP datagram. Multicast supports two
protocols are Internet Group Management Protocol (IGMP) is used by IP hosts to
report their host group memberships to any immediately neighboring multicast
routers and Protocol Independent Multicast-Sparse Mode (PIM-SM) is a protocol
for efficiently routing to multicast groups that may span wide-area (and inter-
domain) internets.
High Availability
The
Load-Balancing
feature is an ideal solution for businesses requiring uninterrupted,
low cost internet connectivity. With multiple Internet connections, it effectively uses the
combined bandwidth of all the internet links resulting in a significant increase in the total
available bandwidth. Also if any Internet connection goes down, uninterrupted internet
connectivity is provided utilizing the serviceable links.
With
Auto Backup
feature, one of the links can function as the Primary WAN Link, and
the other as the Backup Link. When the Primary Link fails, the Backup Link will become
operational and traffic will switchover to this link. And when the Primary Link becomes
serviceable, the traffic will automatically switchback to the Primary Link.
