Re: DHCP SERVER for MULTI-VPN in a VRF

To configure a VPN whereby a client can request IP addresses from a DHCP server using a relay agent, you must define a namespace for the VPN and associate a scope with that namespace. Specifically:

1. Ensure that the relay agents that handle DHCP VPN traffic are configured with a version of Cisco IOS that supports the vpn-id suboption of the relay-agent-info option (82) in DHCP.

2. Coordinate with the IOS relay agent administrator whether the VPN is identified by a VPN ID or a VPN Routing and Forwarding instance (VRF) name. It is rarely both.

3. Configure a namespace in Network Registrar to correspond to the VPN. Associate this namespace with the VPN ID or VRF name.

4. Create a scope for the namespace.
