When policy-based routing (PBR) is being configured, which three criteria can the set
command specify? (Choose three.)
A.
all interfaces in the path toward the destination
B.
all networks in the path toward the destination
C.
adjacent next hop router in the path toward the destination
D.
all routers in the path toward the destination
E.
all interfaces through which the packets can be routed
F.
type of service and precedence in the IP packets
Explanation:
Configuring Policy-Based Routing (PBR):
You can configure PBR by following these steps. Some of the steps may be omitted
depending on your application for PBR. For this example, note the set condition options
listed is step 3 (answers are bolded).
Step 1 Define and configure the route map needed for the policy. This is accomplished with
the route-map command, as discussed previously.
Step 2 Define and configure the match statements the route map will use. The most
common match statements used are the following:
match ip address [access-list number]
The match ip address is used to call a standard, extended, or expanded-range ACL.
match length [min_packet_length_0-2147483647] [max_packet_length_0-
2147483647]
The match length is used to match the Layer 3 packet length, in bytes, with all
associated headers and trailers included. You must enter the minimum and maximum packet
length. Use the match length command to policy route traffic based on packet size. You can
deploy this to route traffic with large or small packet sizes to specific areas of the network.
Step 3 Configure and define the new routing policy with set commands. Multiple set
commands may be used; if multiple commands are used, they are executed in the following
order:
set ip {precedence [value_0-7 | name] | tos [value_0-8 | name]}
set ip next-hop ip_address
set interface interface_name
set ip default next-hop ip_address
set default interface interface_name
Set ip precedence {[1-7]|[routine|critical|flash|flashoverride|immediate|internet|network|priority]}http://www.ciscopress.com/articles/article.asp?p=102092&rl=1
