Layer 3 routing package
StaticRoutes/ECMPStaticRoutesforIPv4andIPv6 • Static and default routes are configurable with next IP address hops to any given destination
• Permitting additional routes creates several options for the network administrator
• The admin can configure multiple next hops to a given destination, intending for the router to load share
across the next hops
• The admin distinguishes static routes by specifying a route preference value: a lower preference value is a
more preferred static route

Advanced Static Routing functions for administrative
traffic control
• Static Reject Routes are configurable to control the traffic destined to a particular network so that it is not
forwarded through the router

• Static reject routes can be typically used to prevent routing loops
• Default routes are configurable as a preference option
In order to facilitate VLAN creation and VLAN routing
using Web GUI, a VLAN Routing Wizard offers
following automated capabilities:
• CreateaVLANandgenerateauniquenameforVLAN
• Add selected ports to the newly created VLAN and remove selected ports from the default VLAN

• Enable tagging on selected ports if the port is in another VLAN
• Disable tagging if a selected port does not exist in another VLAN
• Exclude ports that are not selected from the VLAN
• Enable routing on the VLAN using the IP address and subnet mask entered as logical routing interface

RouterDiscoveryProtocolisanextensiontoICMP
and enables hosts to dynamically discover the IP
address of routers on local IP subnets
• BasedonRFC1256forIPv4
• Routers periodically send router discovery messages to announce their presence to locally-attached
hosts
• The router discovery message advertises one or more IP addresses on the router that hosts can use as their
default gateway
• Hosts can send a router solicitation message asking any router that receives the message to immediately
send a router advertisement
• Router discovery eliminates the need to manually configure a default gateway on each host
• It enables hosts to switch to a different default gateway if one goes down
