Network requirements

As shown in
internal network. Router A and Router B act as the egress routers and connect to external networks
192.168.1.0/24 and 192.168.2.0/24, respectively.
Configure Router A as the default gateway for the hosts. Packets to the external networks can be
correctly routed.

Configuration procedure

1. Configure Router A:
# Specify an IP address for GigabitEthernet 2/1/1.
<RouterA> system-view
[RouterA] interface gigabitethernet 2/1/1
[RouterA-GigabitEthernet2/1/1] ip address 10.154.5.1 24
# Enable IRDP on GigabitEthernet 2/1/1.
[RouterA-GigabitEthernet2/1/1] ip irdp
# Specify preference 1000 for advertised IP addresses on GigabitEthernet 2/1/1.
[RouterA-GigabitEthernet2/1/1] ip irdp preference 1000

Remarks
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.
