Layer 3
Bidirectional
forwarding
detection (BFD)
Provides rapid failure detection in links with adjacent routers (see BFD commands).
Border Gateway
Protocol (BGP)
Provides an external gateway protocol that transmits inter-domain routing information within and
between autonomous systems (see BGP Commands).
Equal Cost Multi-
Path (ECMP)
Provides next-hop packet forwarding to a single destination over multiple best paths (see ECMP
Commands).
IPv4 Routing Provides forwarding of packets to a destination IP address, based on a routing table. This routing table
defines how packets are routed — dynamically, broadcasted directly to, using proxy ARP, as well as what
type of information is included with the packets (see IPv4 Routing Commands).
IPv6 Routing Provides routing for the IPv6 address space, stateless auto-configuration, header format simplifications,
and improved support for options and extensions (see IPv6 Routing Commands).
Open Shortest
Path First
(OSPF)
Provides a link-state routing protocol that communicates with all other devices in the same autonomous
system area using link-state advertisements (LSAs). OS10 supports up to 10,000 OSPF routes for
OSPFv2 to designate up to 8,000 routes as external, and up to 2,000 as inter/intra area routes (see
OSPF Commands).
Virtual Router
Redundancy
Protocol (VRRP)
Provides a mechanism to eliminate a single point of failure in a statically routed network (see VRRP
Commands).
Virtual Routing
and Forwarding
(VRF)
Provides a mechanism to partition a physical router into multiple virtual routers (see VRF Commands).
Configuration notes
Dell EMC PowerSwitch S4200-ON Series:
Though it is possible to configure more VRIDs in VRRP, the S4200-ON Series switches support only up to 16 VRIDs. This
number decreases when VLT peer routing is enabled.
Virtual routing and forwarding
VRF partitions a physical router into multiple virtual routers (VRs). The control and data plane are isolated in each VR; traffic
does not flow across VRs. VRF allows multiple instances of routing tables to co-exist within the same router simultaneously.
OS10 supports a management VRF instance, a default VRF instance, and a maximum of 512 non-default VRF instances. Use the
default and non-default VRF instances to configure routing.
You can move the management interface from the default to management VRF instance. You need not create the management
VRF instance as it already exists in the system by default.
By default, OS10 initially assigns all physical interfaces and all logical interfaces to the default VRF instance.
Configure management VRF
You can assign only management interfaces to the management VRF instance.
Before you assign the management interface to the management VRF instance, delete all the configured settings, including the
IP address, on the management interface.
1. Enter the ip vrf management command in CONFIGURATION mode. Use Non-Transaction-Based Configuration mode
only. Do not use Transaction-Based mode.
