The device uses ICMP Router Discovery Protocol (IRDP) to advertise the IP addresses of its router
interfaces to directly attached hosts. IRDP is disabled by default. You can enable it globally or on

NOTE
You can configure IRDP parameters only an individual port basis. To do so, IRDP must be disabled
globally and enabled only on individual ports. You cannot configure IRDP parameters if the feature

Example
BigIron RX(config)# access-list 10 deny host 209.157.22.26 log
BigIron RX(config)# access-list 10 deny 209.157.29.12 log
BigIron RX(config)# access-list 10 deny host IPHost1 log
BigIron RX(config)# access-list 10 permit any
BigIron RX(config)# write memory
BigIron RX(config)# ip receive access-list 10
Syntax: [no] ip receive access-list <num>
If you enable IRDP globally, all ports use the default values for the IRDP parameters.
If you leave IRDP disabled globally but enable it on individual ports, you also can configure the
IRDP parameters on an individual port basis.
