Layer 3 Routing Commands 1494
The addition of a preference option has a side benefit. The preference option
allows the operator to control the preference of individual static routes
relative to routes learned from other sources (such as OSPF). When routes
from different sources have the same preference, Dell EMC Networking
routing prefers a static route over a dynamic route.
Static Reject Routes
To administratively control the traffic destined to a particular network so that
it is not forwarded through the router, Dell EMC Networking enables
configuring a static reject route for that network on the router. Such traffic is
discarded and an ICMP destination unreachable message is sent back to the
source. Static reject routes are typically used to prevent routing loops.
Default Routes
Dell EMC Networking routing provides a preference option for the
configuration of default routes. A configured default route is treated exactly
like a static route. Therefore, default routes and static routes have the same
default preference (1).
encapsulation
Use the encapsulation command in Interface Configuration (VLAN) mode
to configure the Link Layer encapsulation type for the packet. Routed frames
are always Ethernet-encapsulated when a frame is routed to a VLAN.
Syntax
encapsulation {ethernet | snap}
• ethernet — Specifies Ethernet encapsulation.
• snap — Specifies SNAP encapsulation.
Default Configuration
Ethernet encapsulation is the default configuration.
