I have IOS-XE switches running 16.12.7 code. They are configured in HSRP group. Every time client connects both routers active and standby use the "IP helper address" to forwarded the DHCP request via the active and the standby routers. I am trying to configure DHCP aware on them so only the active router forward the request and the standby not.
I know how to do it in IOS but not IOS XE. the redundancy command or adding a group name and add it to the relay command are not available in IOS-XE.
Here is the interface config:
interface Vlan100
description test
ip address 10.1.1.1 255.255.255.0
ip helper-address 10.10.10.10
ip helper-address 10.10.20.10
no ip redirects
ip pim sparse-dense-mode
standby 1 ip 1.1.1.1
standby 1 priority 110
standby 1 preempt delay minimum 300
standby 1 authentication xxxxxx
