One reference is in the reference guide for version 9.21:
http://127.0.0.1:8080/cc/td/doc/product/software/ssr921/rpcr/79014.htm#xtocid21
76130
Later reference guides say this command will be removed in a later
release. Still there in 12.0(7)T.
You can also do a CD search for "ip gdp irdp"and you will get 10's of
hits. Below is what is in the
reference guide:
ip gdp irdp
Use the ip gdp irdp interface configuration command to configure the
router discovery feature using the ICMP
Router Discovery Protocol (IRDP). Use the no ip gdp irdp command to
disable this feature.
ip gdp irdp
no ip gdp irdp
Syntax Description
This command has no arguments or keywords.
Default
Disabled
Command Mode
Interface configuration
Usage Guidelines
IP routing must be disabled before you can configure this feature.
Example
The following example configures router discovery using IRDP on the
Ethernet 0 interface:
!
interface ethernet 0
ip gdp irdp
