Configuring IP Routing
9-9
2. Refer to Table9-3 to configure the IP Global Configuration
dialog box.
Table 9-3. IP Global Configuration Parameters
Parameter Allows you to...
IP Unicast
Forwarding
Disable IP Unicast. The default setting is Enable.
IP Multicast
Forwarding
Enable IP multicast on a global basis. This affects all IP RIP
interfaces set up to use multicast protocols. The default setting is
Disable.
IP Source Routing Disable IP source routing globally. The default setting is Enable.
VRRP Disable VRRP globally. The default setting is Enable.
BOOTP/DHCP
Relay Agent
Disable client requests for an IP address and forwards their
requests to a server. This agent also relays responses from the
server to the client. The default setting is Enable.
Limit Proxy ARP
to Same Network
Enable Proxy ARP on the same network. When enabled, the
router only responds to ARP requests when the source and target
IP address are in the same IP network and different IP subnets.
When disabled, the router only responds to ARP requests when
the source and target IP address are in different networks.
The default setting is Disable.
Use Default
Route for Proxy
ARPs
Disable the use of the default route on your Cajun switch as the
route for Proxy ARPs. For example, if you have a default route
configured to reach the 0.0.0.0 IP address, then any ARP request
that does not match any of the other routes in your IP routing
table will automatically go to this default route. The default
setting is Enable.
Maximum
Number of
Routes
Enter the maximum number of routes that you want added to
the routing table. The default number of routes is 16384.
Note: These routes refer only to IP Unicast entries.
Maximum
Number of ARP
Cache Entries
Enter the maximum number of ARP cache entries. ARP entries
refers to the space available for the IP address table. When you
increase the number of entries, it may cause the table to be
relearned more frequently. Consequently, it will make address
space usage more efficient. The default maximum number of
entries is 16384.
Route Preference
by Protocol
This section describes the routing preferences set up according to
the network administrator’s preferences. These preferences are
normally set up using the most to least trust. For example, local
routes are normally considered to have more trust or a higher
preference, while OSPF external routes are considered to have less
trust or a lower preference. These preferences can be overridden,
but careful consideration must be given when setting each.
Local Routes Enter a preference value for local routes.
