Our regional offices have Firepower FTD devices (without FMC), each with two VTI interfaces to the data center, routing via BGP.
We want to use DHCP Relay to point to a remote DHCP server (due to FTD's DHCP lacking needed config options). I don't want to hard code the name of a VTI interface in the DHCP Relay FlexObject to avoid a single point of failure. Is is possible to use the local routing table to chose the best interface to reach the remote DHCP server?
Current command: dhcprelay server 10.10.10.10 vti1 <-- don't want that vti hard coded
I have tried the following.
dhcprelay server 10.10.10.10 vti1
dhcprelay server 10.10.10.10 vti2
The Firepower accepts the config, but only the 2nd command appears to be active.
