Control Plane
The control plane of Ubigate iBG1000 includes routing protocols for L3 routing
and spanning tree protocols for L2 packet processing, more specifically:
L2 Control Protocol consisting of VLAN management
Unicast Protocols, consisting of Open Shortest Path First (OSPF) and
Routing Information Protocol (RIP)
Multicast Protocols, consisting of Protocol Independent Multicast-Sparse
Mode (PIM-SM), PIM-Source Specific Multicast (PIM-SSM), and Distance
Vector-Multicast Routing Protocol (DVMRP)
WAN Protocols, consisting of PPP, Frame Relay, PPP over Frame Relay,
High-level Data Link Control procedure (HDLC) and ISDN
Unicast Routing Protocols
Interior Gateway Protocols such as RIP and OSPF are supported in Ubigate
iBG1000.

Description
RIP v1/v2: Routing
Information Protocol
Routing Information Protocol (RIP) is a classical distance-
vector routing protocol. It is simple to implement and
performs good for small networks. Distance Vector Routing
requires that each node maintain the distance from itself to
each possible destination. The distances are computed
using the information in neighbor’s distance vectors.
RIP version 1 (defined in RFC 1058) has been later
augmented by RIP version 2 (RFC 2453) to increase its
usefulness. RIP 2 enabled RIP messages to carry more
information, which permitted the use of a simple
authentication mechanism to secure table updates.
More importantly, RIP 2 supported subnet masks, a
critical feature that was not available in RIP.
