Basic IP parameters and defaults – Layer 3 Switches
Reverse ARP 
(RARP)
An IP mechanism a host can use to request an IP 
address from a directly attached router when the 
host boots. 
Enabled
Static RARP 
entries
An IP address you place in the RARP table for RARP 
requests from hosts. 
NOTE: You must enter the RARP entries manually. 
The Layer 3 Switch does not have a 
mechanism for learning or dynamically 
generating RARP entries.
No entries
Maximum 
BootP relay 
hops
The maximum number of hops away a BootP server 
can be located from a router and still be used by the 
router clients for network booting.
Four
Domain name 
for Domain 
Name Server 
(DNS) resolver
A domain name (example: Brocade.router.com) you 
can use in place of an IP address for certain 
operations such as IP pings, trace routes, and Telnet 
management connections to the router.
None configured
DNS default 
gateway 
addresses
A list of gateways attached to the router through 
which clients attached to the router can reach DNSs.
None configured
IP load sharing
A feature that enables the router to balance traffic 
to a specific destination across multiple equal-cost 
paths. 
NOTE: Load sharing is sometimes called Equal Cost 
Multi Path (ECMP).
Enabled
Maximum IP 
load sharing 
paths
The maximum number of equal-cost paths across 
which the Layer 3 Switch is allowed to distribute 
traffic.
Four
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
Disabled
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
Static route
An IP route you place in the IP route table.
No entries
Source 
interface
The IP address the router uses as the source 
address for Telnet, RADIUS, or TACACS/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.
