Configuring IP Routing (Layer 3)

Enabling IP Routing

To enable IP routing for an IP interface:

1.In the IP Configuration section of the Web Agent window, click Global Configuration. The IP Global Configuration dialog box opens.

Note: IP routing is disabled by default.

2.Use Table 7-2 to configure your global configuration setup:

Table 7-2.IP Global Configuration Parameters

Parameter

Allows you to...

 

 

IP Unicast

Enable or disable IP unicast on a global basis.

Forwarding

 

 

 

IP Multicast

Enable or disable IP multicast on a global basis. This affects all IP RIP

Forwarding

interfaces set up to use multicast protocols.

 

 

IP Source Routing

Enable or disable strict source routing and loose source routing globally.

 

 

VRRP

Enable or disable VRRP globally.

 

 

BOOTP/DHCP

Accepts client requests for an IP address and forwards them to a server.

Relay Agent

This agent also relays responses from the server to the client.

 

 

Limit Proxy ARP

Enable or disable Proxy ARP on the same network. When enabled, the

to Same Network

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.

 

 

Use Default Route

Enable or disable the use of the default route on your Cajun switch as the

for Proxy ARPs

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.

 

 

Maximum

Specify the maximum number of routes that can be added to the routing

Number of Routes

table. The default number of routes is 16384.

 

Note: These routes refer only to IP Unicast entries.

 

 

Maximum

Specify the maximum number of ARP cache entries. Refers to the space

Number of ARP

available for the IP address table. When you increase the number of

Cache Entries

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.
