Policy Route Settings
Policy Based routing is a method used by the Switch to
give specified devices a cleaner path to the Internet.
Used in conjunction with the Access Profile feature, the
Switch will identify traffic originating from a device
using the Access Profile feature and forward it on to a
next hop router that has a more direct connection to
the Internet than the normal routing scheme of your
network.
Take the example adjacent picture. Let’s say that the
PC with IP address 10.1.1.1 belongs to the manager of
a company while the other PCs belong to employees.
The network administrator hopes to circumvent
network traffic by configuring the Policy Routing Switch
to make a more direct connection to the Internet using
a next hop router (10.2.2.2) that is directly attached to
a Gateway router (10.3.3.3), thus totally avoiding the
normal network and its related traffic. To accomplish
this, the user must configure the Access Profile feature
of the Switch to have the PC, with IP address 10.1.1.1
as the Source IP address and the Internet address as
the destination IP address (learned through routing
protocols), along with other pertinent information. Next,
the administrator must configure the Policy Route
window to be enabled for this Access Profile and its
associated rule, and the Next Hop Router’s IP address
(10.2.2.2) must be set. Finally, this Policy Route entry
must be enabled.
Figure 6-5 Policy Base Routing Example window
Once completed, the Switch will identify the IP address using the Access Profile function, recognize that is has a
Policy Based route, and then forward the information on to the specified next hop router, that will, in turn, relay
packets to the gateway router. Thus, the new, cleaner path to the Internet has been formed.
There are some restrictions and cautions when implementing this feature:
1. The access profile must first be created, along with the accompanying rule. If the administrator attempts to
enable this feature without the access profile, an error message will be produced.
2. If the access profile is configured as Deny, the packet will be dropped and not forwarded to the next hop
destination.
3. If the administrator deletes a rule or profile that is directly linked to a configured policy route, and error
message will be prompted to the administrator.
