interfaces in WeOS). Routing can be disabled, and the WeOS device will then act
as a VLAN capable switch.
26.1.3
Learning routing information from different sources
A WeOS device will learn about routing information by manual configuration (con-
nected interfaces or static routes), dynamic address assignment (e.g., DHCP), or
via dynamic routing protocols (OSPF and RIP). As described in
and
a router is able to redistribute external routing information into an OSPF or RIP
routing domain.
In some situations a router will learn the route to the same destination through
different mechanisms. In this case, the route to use will depend on the adminis-
trative distance (or simply ”admin distance”) associated with the involved routing
mechanisms. A route with a lower admin distance will be prioritised over a router
with higher admin distance.
Connected routes are always preferred (they have admin distance ’0’ (zero)). In
WeOS the admin distance of static routes, and routes learnt dynamically via RIP
and OSPF can be configured, but defaults to the values shown in the table below.
Routes learnt dynamically via DHCP or PPP will have admin distance according to
the distance assigned to the associated interface, see

Configuring static routes with higher administrative distance than set for OSPF
or RIP is also referred to floating static routes, see
for further
details.
26.1.4
Static routing
WeOS supports static IP routing. With static routing a WeOS devices can specify
the next hop router to use to reach a given IP subnet, or add additional (directly
attached) subnets to a local interface.
