IP Routing in WeOS
In addition to switching (layer-2), WeOS devices (with proper WeOS level) are able
to route data packets (layer-3), i.e., they are routing switches. The WeOS routing
support includes static routing and dynamic unicast routing via OSPF and RIP,
static multicast routing, as well as other useful router features such as firewall,
NAT, and VRRP.
This chapter introduces the IP routing capabilities in WeOS in general. More in-
formation on dynamic routing is found in
chapters 27 (OSPF) and 28 (RIP), while
static multicast routing support is described in chapter 29 . Supplementary router
services are covered in the chapters to follow: VRRP in chapter 30 , and firewall
and NAT in chapter 31 .
Support for VPN and tunneling techniques are presented separately, see part IV .
26.1 Summary of WeOS Routing and Router Features
Table 26.1 presents the routing and router features available in WeOS.
26.1.1 Introduction to WeOS Routing and Router Features
IP routing enables us to connect our networks together, and to let (TCP/IP) devices
communicate across networks of different type and topology, and possibly over
multiple network ”hops” and long distances. A router looks at the destination
IP address carried within each IP packet, consults its routing table to make a
