5 Layer 3 Bidirectional Provides rapid failure detection in links with adjacent routers (see BFD commands). forwarding detection (BFD) 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 MultiPath (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 Provides a link-state routing protocol that communicates with all other devices in the same autonomous system First (OSPF) 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 Provides a mechanism to partition a physical router into multiple virtual routers (see VRF Commands). Forwarding (VRF) Virtual routing and forwarding Virtual routing and forwarding (VRF) allows to partition a physical router into multiple virtual routers. The control and data plane are isolated in each virtual router (VR) so that traffic does not flow across VRs. VRF allows multiple instances of routing tables to co-exist within the same router at the same time. OS 10 supports a management VRF instance, a default VRF instance, and up to 16 non-default VRF instances. Use the default and nondefault VRF instances to configure routing. You can move the management interface from the default to management VRF instance. 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, remove all the configured settings, including the IP address, on the management interface. 1 Enter the ip vrf management command in the CONFIGURATION mode. Use non-transaction-based configuration mode only. Do not use transaction-based mode. 2 Add the management interface by using the interface management command in the VRF CONFIGURATION mode.

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
).
Virtual routing and forwarding
Virtual routing and forwarding (VRF) allows to partition a physical router into multiple virtual routers. The control and data plane are isolated
in each virtual router (VR) so that
traffic
does not
flow
across VRs. VRF allows multiple instances of routing tables to co-exist within the
same router at the same time.
OS 10 supports a management VRF instance, a default VRF instance, and up to 16 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.
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, remove all the
configured
settings, including the IP
address, on the management interface.
1
Enter the
ip vrf management
command in the CONFIGURATION mode. Use non-transaction-based
configuration
mode only. Do
not use transaction-based mode.
2
Add the management interface by using the
interface management
command in the VRF CONFIGURATION mode.
