Configuring the Router-Discovery Max-Advertisement-Interval

Chapter 1 Configuring Interfaces and Circuits

Configuring Circuits

Configuring the Router-Discovery Max-Advertisement-Interval

By default, the maximum interval timer used for router discovery advertisement from the circuit VLAN is 600 (10 minutes). Use the router-discoverymax-advertisement-intervalcommand to configure the maximum interval timer used for router discovery advertisement from the circuit VLAN. This command defines the maximum interval, in seconds, between sending advertisements. Enter an integer from 4 to 1800.

For example:

(config-circuit[VLAN7])#router-discovery max-advertisement-interval

300

To restore the router discovery maximum advertisement interval to the default of 600, enter:

(config-circuit[VLAN7])# no router-discovery

max-advertisement-interval

Configuring the Router-Discovery Min-Advertisement-Interval

By default, the minimum router advertisement interval is 0.75 times the maximum advertisement value. To configure the minimum interval timer used for router discovery advertisement from the circuit VLAN, use the router-discoverymin-advertisement-intervalcommand. This command defines the minimum interval, in seconds, between sending advertisements. Enter an integer from 0 to 1800.

The default is 0.75 times the max-advertisement-interval. If this value is greater than 0, it must be less than the value specified using the router-discoverymax-advertisement-intervalcommand.

For example:

(config-circuit[VLAN7])#router-discovery min-advertisement-interval

100

To reset the minimum router advertisement interval to the default of 0.75 times the maximum advertisement value, enter:

(config-circuit[VLAN7])# no router-discovery

min-advertisement-interval
