Use the router-discovery preference command to specify the preference level for
the advertised CSS circuit IP address, relative to other devices on the same
network. The value is an integer from 0 (default) to 65535. If you use the default
value, you do not need to use this command.
For example, to specify a router discovery preference value of 100, enter:
(config-circuit-ip[VLAN7-192.168.1.58])# router-discovery
(config-circuit-ip[VLAN7-192.168.1.58])# router-discovery preference
100
To disable router discovery, enter:
(config-circuit-ip[VLAN7-192.168.1.58])# no router-discovery
To restore the router discovery preference value to the default of 0, enter:
(config-circuit-ip[VLAN7-192.168.1.58])# no router-discovery
preference
Enabling and Disabling a Circuit IP
By default, the IP interface on a circuit is enabled. To disable the IP interfaces on
a circuit, enter:
(config-circuit-ip[VLAN7-172.16.6.58])# no enable
To reenable the IP interface on a circuit, use the enable command. For example:
(config-circuit-ip[VLAN7-172.16.6.58])# enable
Configuring Router-Discovery Protocol Settings for a Circuit
The CSS allows you to enable Router Discovery Protocol (RDP) settings and
define a router discovery preference for each circuit VLAN. RDP announces the
existence of the CSS to hosts by periodically multicasting or broadcasting a router
advertisement to each interface.
Use the circuit command to enter the circuit configuration mode before
configuring RDP for a circuit VLAN.
