Dell SmartFabric OS10 User Guide Release 10.5.3

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 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.
