Enabling IRDP

ICMP Router Discovery Protocol (IRDP) can be enabled globally or on a specific interface.
When IRDP is enabled globally, the parameters are set to default values and cannot be changed. If you enable IRDP on a specific interface, you can configure the following parameters:
  • Packet type
  • Maximum message interval
  • Minimum message interval
  • Hold time
  • Preference

For more details about these IRDP parameters, refer to "IRDP parameters" of ICMP Router Discovery Protocol Configuration.

  1. Enter global configuration mode. 
    device# configure terminal
  2. To enable IRDP choose one of the following options:
    • Enable IRDP globally, go to Step 3.
    • Enable IRDP on a specific interface, go to Step 4.
  3. Enable IRDP in global configuration mode. 
    device(config)# ip irdp
    IRDP is enabled on the IP interfaces on all ports. Each port uses the default values for the IRDP parameters. The parameters are not configurable when IRDP is globally enabled.
  4. Enable IRDP on a specific interface. 
    device(config)# interface ethernet 1/1/3
device(config-if-1/1/3)# ip irdp maxadvertinterval 400
    After entering interface configuration mode for Ethernet interface 1/1/3, IRDP is enabled for the interface and the maximum advertisement interval is set to 400 seconds.
