Everyone I have a doubt about the configuration for the helper address on ASR9000, mainly I try to configure the helper address in this way:
interface type number
ipv4 helper-address vrf vrf_name address
However it doesnt work.
What is the correct way to apply an helper address on my ASR9000 ???
Correct configuration is:
dhcp ipv4 profile DHCP-HELP relay helper-address vrf <VRF> <IP address> ! interface <interface> relay profile DHCP-HELP !
