IRDP configuration example

Network requirements

As shown in
in the internal network of a company. Switch A and Switch B serve as the egress devices and connect to
external networks 192.168.1.0/24 and 192.168.2.0/24, respectively.
Configure Switch A as the default gateway for the hosts. Packets to the external networks can be correctly
routed.
Figure 51, Host A and Host B that run the Linux operating systems support IRDP, and they are

Remarks
By default, IRDP is disabled.
After IRDP is enabled on an interface,
the IRDP configuration takes effect,
and the device sends RA messages
out of the interface.
The default preference is 0.
The default lifetime is 1800 seconds.
The specified lifetime applies to all
advertised IP addresses, including
the IP addresses of the interface and
proxy-advertised IP addresses on the
interface.
The lifetime of the advertised IP
addresses cannot be shorter than the
maximum advertising interval.
By default, the maximum interval is
600 seconds and the minimum
interval is 3/4 of the maximum
interval.
By default, RAs use the broadcast
address 255.255.255.255 as the
destination IP address.
Repeat this step to specify multiple
proxy-advertised IP addresses.
By default, no IP address is specified.
You can specify a maximum of four
proxy-advertised IP addresses on an
interface.
