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-discovery
limited-broadcast command 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
