NOTE:
When you stop or restart an interface, interface changes are discarded if they have
not been saved.
Interface Routing and Filtering
After the eth add and eth ip addr commands define the Ethernet logical interface,
other eth commands can reference it, including:
-> eth ip addroute
Adds an Ethernet IP route that uses the logical Ethernet interface. The route is added
to the default routing table.
-> eth ip bindroute
Adds an Ethernet IP route that uses the logical Ethernet interface. The route is added
to a virtual routing table
-> eth ip filter
Manages IP filters for the logical Ethernet interface. Lists of input, output, and forward
filters may be defined for the interface
-> eth ip options
Sets RIP options for the logical interface; these options set IP routing information
protocol controls
NOTE:
In general, logical interface commands are not effective until you save the change
and either restart the logical interface or reboot the router. However, the eth ip
bindroute and eth ip filter commands are effective immediately if the logical Ethernet
interface is already active.
Virtual Routing Tables
The virtual routing feature allows you to define multiple routing tables. This is also
known as IP virtual router support.
To define a new routing table, you must specify a name for the routing table and a
range of IP source addresses that use that table. The router determines which routing
table to use based on the source address in the packet. For example, if the router
receives a packet whose source address is 192.168.254.10, it checks if that address
is within the address range defined for a virtual routing table. If it is, the virtual routing
table is used to route the packet. If it is not, the default routing table is used instead.
