Configuring Circuits

This section includes the following topics:

•Configuring the Router-Discovery Lifetime

•Configuring Router-Discovery Limited-Broadcast

•Configuring the Router-Discovery Max-Advertisement-Interval

•Configuring the Router-Discovery Min-Advertisement-Interval

Configuring the Router-Discovery Lifetime

By default, the maximum age that hosts remember router advertisements is three times the max-advertisement-interval. Use the router-discovery lifetime command to configure the maximum age, in seconds. Enter an integer between 0 and 9000 seconds.

For example:

(config-circuit[VLAN7])#router-discovery lifetime 600

To reset the time to the default of three times the max-advertisement-interval, enter:

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

Configuring Router-Discovery Limited-Broadcast

By default, the CSS transmits router discovery packets using the limited broadcast address is 224.0.0.1 (the “all-hosts” multicast address). Use the router-discoverylimited-broadcastcommand to transmit router discovery packets using the limited broadcast address 255.255.255.255.

For example:

(config-circuit[VLAN7])#router-discovery limited-broadcast

To revert to the default of 224.0.0.1, enter:

(config-circuit[VLAN7)#no router-discovery limited-broadcast
