• VRRPE
By default, IP routing is enabled on the device. All other protocols are disabled, so you must enable
them to configure and use them.
NOTE
The following protocols require a system reset before the protocol will be active on the system: PIM,
DVMRP, RIP, FSRP. To reset a system, enter the reload command at the privileged level of the CLI.
To enable a protocol on a device, enter router at the global CONFIG level, followed by the protocol to
be enabled. The following example shows how to enable OSPF.
BigIron RX(config)# router ospf
BigIron RX(config-ospf-router)# end
BigIron RX# write memory
BigIron RX# reload
Syntax: router bgp | dvmrp | ospf | pim | rip | vrrp | vrrpe
Displaying and modifying system parameter default settings
The device has default table sizes for the following parameters. The table sizes determine the
maximum number of entries the tables can hold. You can adjust individual table sizes to
accommodate your configuration needs.
• MAC address entries
• Layer 2 Port VLANs supported on a system
• Layer 3 Protocol VLANs supported on a system
• Layer 4 sessions supported
• IP cache size
• ARP entries
• IP routes
• IP route filters
• IP subnets per port and per device
• Static routes
The tables you can configure as well the defaults and valid ranges for each table differ depending
on the device you are configuring.
NOTE
If you increase the number of subnet addresses you can configure on each port to a higher amount,
you might also need to increase the total number of subnets that you can configure on the device.
NOTE
Changing the table size for a parameter reconfigures the device’s memory. Whenever you
reconfigure the memory on a device, you must save the change to the startup configuration file, then
reload the software to place the change into effect.
To display the configurable tables, their defaults and maximum values, enter the following
command at any level of the CLI.
