(a) Confirm output interface using policy routing function
Step 1.
Log in to this router.
Step 2.
Using the
show ip policy
command, inspect the configuration definition of the
policy routing input interface and the status of the policy routing output
interface.
[Example]
Confirm the output destination used by a policy routing function when the input
interface of a packet that cannot be communicated is tokyo and when the
transmission source IP address is 200.1.4.5.
Step 1.
Log in to this router.
Step 2.
Enter
show ip policy interface tokyo
:
> show ip policy interface tokyo
tokyo 1,2
>
Step 3.
Confirm the condition number used in input interface tokyo.
In the example described above,
Step 4.
Display the detail information of the conditions confirmed in step 3.
Enter
show ip local policy interface tokyo 1 2
:
> show ip local policy interface tokyo 1 2
ip source: 200.1.4.0 - 200.1.4.255
ip destination: 200.1.7.0 - 200.1.8.255
current policy route
Policy Group Name route1
Output Interface tokyo3
Next Hop IP address 200. 1. 10. 1
ip source: 200.1.5.0 - 200.1.5.255
ip destination: 200.1.19.0 - 200.1.20.255
current policy route
Policy Group Name route2
Output Interface yokohama
Next Hop IP address 200. 1. 50. 2
>
Step 5.
Confirm the contents of conditions and the output destination at that time.
Compare the contents of a packet that cannot be communicated and
confirm the policy routing group name under conditions in which the
contents match.
Step 6.
Confirm the state of the employed policy group. Enter
show ip cache policy
route1
:
> show ip cache policy route1
priority Interface Name status Nexthop
1 tokyo1 Down 200. 1. 1. 2
2 tokyo1 Down 200. 1. 2. 2
3 tokyo2 Down 200. 1. 8. 3
*> 4 tokyo3 Down 200. 1. 10. 1 default
>
Step 7.
A packet is discarded because it cannot be output due to a defective output
destination interface. Recheck the policy information setting of the current
configuration definition information and follow “Section 7.4,
“Communication failure in network interface” on page 7-11.
