Hi,

Here is a question.

   R3-------------R2------vlan62-------R6
(DHCP SV)

R3 is DHCP SV for vlan26.
R2 & R6 are redundant IRDP routers for vlan26; R2 is a primary router.
What gw address does R3 provide for users on valn26?
Or a default-router command is not needed?

Crrect me if my solution is wrong.

R3;
ip dhcp excluded-address 148.11.62.2
ip dhcp excluded-address 148.11.62.6
!
ip dhcp pool 1
   network 148.11.62.0 255.255.255.0
   dns-server 200.200.200.200 100.100.100.100
   domain-name cisco.com
   default-router 148.11.62.2 148.11.62.6

R2;
interface Ethernet1
 ip address 148.11.62.2 255.255.255.0
 ip helper-address 148.11.36.3
 ip irdp
 ip irdp maxadvertinterval 30
 ip irdp minadvertinterval 10
 ip irdp holdtime 90
 ip irdp preference 100
!

R6;
interface Ethernet1
 ip address 148.11.62.6 255.255.255.0
 ip helper-address 148.11.36.3
 ip irdp
 ip irdp maxadvertinterval 30
 ip irdp minadvertinterval 10
 ip irdp holdtime 90
 ip irdp preference -100
!

Please give me any comment.
