ip dhcp pool poolB2
relay source 10.4.0.0 255.255.0.0
class poolB2
relay target 10.10.2.1
Configuration of secure ARP for the relay will use the same configuration command as secure ARP
already uses on a DHCP server by using the update arp command in address-pool configuration mode.
If the system is allocating an address from this address pool, it will add secure ARP. If the system is
relaying a packet using this address pool, it will also add secure ARP.
Dynamic VPN Selection: Example
The following example shows how to configure dynamic VPN selection using a multiservice interface:
