To configure other ARP parameters, refer to
To increase the size of the ARP cache and static ARP table, refer to the following:
•
For dynamic entries, refer to the “Displaying and modifying default settings for system
parameters”. The ip-arp parameter controls the ARP cache size.
IP route table
The IP route table contains paths to IP destinations.
The IP route table can receive the paths from the following sources:
•
A directly-connected destination, which means there are no router hops to the destination
•
A static IP route, which is a user-configured route
•
A route learned through RIP
•
A route learned through OSPF
•
A route learned through IS-IS
•
A route learned through BGP4
The IP route table contains the best path to a destination:
•
When the software receives paths from more than one of the sources listed above, the
software compares the administrative distance of each path and selects the path with the
lowest administrative distance. The administrative distance is a protocol-independent value
from 1 – 255.
•
When the software receives two or more best paths from the same source and the paths have
the same metric (cost), the software can load share traffic among the paths based on Layer 2,
Layer 3 and TCP/UDP information.
Example : IP route table
Each IP route table entry contains the destination’s IP address and subnet mask and the IP
address of the next-hop router interface to the destination. Each entry also indicates the port
attached to the destination or the next-hop to the destination, the route’s IP metric (cost), and the
type. The type indicates how the IP route table received the route.
To display the IP route table, refer to
“Displaying the IP route table”
.
To configure a static IP route, refer to
.
To clear a route from the IP route table, refer to
.
To increase the size of the IP route table for learned and static routes, refer to “Displaying and
modifying default settings for system parameters”.
.Consider the following:
•
For learned routes, modify the ip-route parameter.
•
For static routes, modify the ip-static-route parameter.
