• Use Global Destinations Only—Select to forward packets to the DHCPv6 global
destination servers only.
• IPv6 Address Type—Enter the type of the destination address to which client messages
are forwarded. The address type can be Link Local, Global or Multicast
(All_DHCP_Relay_Agents_and_Servers).
• DHCPv6 Server IP Address—Enter the address of the DHCPv6 server to which
packets are forwarded.
• Destination IPv6 Interface—Enter the interface on which packets are transmitted
when the address type of the DHCPv6 server is Link Local or Multicast.
Click Apply. The Running Configuration file is updated.
Policy-based Routing (PBR) provides a means for routing selected packets to a next hop
address based on packet fields, using ACLs for classification. PBR lessens reliance on routes
derived from routing protocols.
Route Maps
Route maps are the means used to configure PBR.
To add a route map:
Click IP Configuration > Policy Based Routing > Route Maps.
Click Add and enter the parameters:
• Route Map Name—Select one of the following options for defining a route map:
- Use existing map—Select a route map that was previously defined to add a new rule
to it.
- Create new map—Enter the name of a new route map.
• Sequence Number—Number that indicates the position/priority of rules in a specified
route map. If a route map has more than one rule (ACL) defined on it, the sequence
number determines the order in which the packets will be matched against the ACLs
(from lower to higher number).
