Basic IPv4 Routing
Internet Protocol (IP) is a network-layer (Layer 3) protocol that contains addressing and control informa-
tion that allow packets to be forwarded on a network. IP is the primary network-layer protocol in the Inter-
net protocol suite. Along with the Transmission Control Protocol (TCP), IP represents the heart of the
Internet protocols. IP is associated with several Layer 3 and Layer 4 protocols. These protocols are built
into the base code loaded on the switch and they include:
•Transmission Control Protocol (TCP)
•User Datagram Protocol (UDP)
•Bootstrap Protocol (BOOTP)/Dynamic Host Configuration Protocol (DHCP)
•Simple Network Management Protocol (SNMP)
•Telnet
•File Transfer Protocol (FTP)
•Address Resolution Protocol (ARP)
•Internet Control Message Protocol (ICMP)
•RIP I / RIP II
The base IP software allows one to configure an IP router interface, static routes, a default route, the
Address Resolution Protocol (ARP), the router primary address, the router ID, the Time-to-Live (TTL)
Value, IP-directed broadcasts, and the Internet Control Message Protocol (ICMP). In addition, this soft-
ware allows one to trace an IP route, display Transmission Control Protocol (TCP) information, and
display User Datagram Protocol (UDP) information.
OmniSwitch 9000 supports hardware routing/flooding to static arp with multicast MAC address.
Note. The switch operates only in single MAC router mode. In this mode, each router VLAN is assigned
the same MAC address, which is the base chassis MAC address for the switch.
BGP4
The Border Gateway Protocol (BGP) is an exterior routing protocol that guarantees the loop-free exchange
of routing information between autonomous systems. There are three versions of the BGP protocol—
versions 2, 3, and 4. The Alcatel-Lucent implementation supports BGP version 4 as defined in RFC 1771.
The Alcatel-Lucent implementation of BGP is designed for enterprise networks, specifically for border
routers handling a public network connection, such as the organization’s Internet Service Provider (ISP)
link. Up to 65,000 route table entries and next hop routes can be supported by BGP.
BGP Graceful Restart
BGP Graceful Restart is now supported and is enabled by default. On OmniSwitch devices in a redundant
CMM configuration, during a CMM takeover/failover, interdomain routing is disrupted. Alcatel-Lucent
Operating System BGP needs to retain forwarding information and also help a peering router performing a
BGP restart to support continuous forwarding for inter-domain traffic flows by following the BGP grace-
ful restart mechanism.
The 6.1.3.R01 release provides support for this feature on the OmniSwitch 6800 Series, OmniSwitch 6850
Series, and OmniSwitch 9000 Series.
