IP interface parameters
Table 47 lists the interface-level IP parameters for the device, their default values, and where to
find configuration information.
IP load sharing A Brocade feature that enables the router to balance traffic to a
specific destination across multiple equal-cost paths.
Load sharing is based on a combination of destination MAC
address, source MAC address, destination IP address, source IP
address, and IP protocol.
NOTE: Load sharing is sometimes called Equal Cost Multi Path
(ECMP).
Enabled page 211
Maximum IP load
sharing paths
The maximum number of equal-cost paths across which the
device is allowed to distribute traffic.

Origination of default
routes
You can enable a router to originate default routes for the
following route exchange protocols, on an individual protocol
basis:
• RIP
• OSPF
• BGP4

Default network
route
The router uses the default network route if the IP route table
does not contain a route to the destination and also does not
contain an explicit default route (0.0.0.0 0.0.0.0 or 0.0.0.0/0).
None configured page 211
Static route An IP route you place in the IP route table. No entries page 201
Source interface The IP address the router uses as the source address for Telnet,
RADIUS, or TACACS and TACACS+ packets originated by the router.
The router can select the source address based on either of the
following:
• The lowest-numbered IP address on the interface the packet
is sent on.
• The lowest-numbered IP address on a specific interface. The
address is used as the source for all packets of the specified
type regardless of interface the packet is sent on.
The lowest-numbered IP
address on the interface the
packet is sent on.
