How do I configure unicast RPF and fail filters in dynamic profiles?
Configuring unicast RPF and fail filters in dynamic profiles:
- For dynamic profiles in a DHCP environment, configure a filter to pass DHCP packets. By default, the reverse path forwarding (RPF) check prevents DHCP packets from being accepted on interfaces protected by the RPF check.
- In contrast to statically configured fail filters, reverse path forwarding (RPF)-check fail filters used in a dynamic profile cannot be specific to a particular interface.
