Displaying The Ospf Configuration; Configuring A Vpi Range (Optional) - Cisco Catalyst 8540 MSR Configuration Manual

Configuring Tag Switching
An IP address of 1.1.1.1 with a subnet mask of 255.255.255.0 is entered as an IP network prefix of
Note
1.1.1.0 with a subnet mask of 0.0.0.255. Likewise, an IP address of 1.2.1.1 with a subnet mask of
255.255.255.0 is entered as an IP network prefix of 1.2.1.0 with a subnet mask of 0.0.0.255.
Switch(config)# router ospf 10000
Switch(config-router)# network 1.1.1.0 0.0.0.255 area 0

Displaying the OSPF Configuration

To display the OSPF configuration, use the following privileged EXEC command:
Command
show ip ospf
The following example shows the OSPF configuration using the show ip ospf privileged EXEC
command:
Switch# show ip ospf
Routing Process "ospf 10000" with ID 1.0.1.11
Supports only single TOS(TOS0) routes
SPF schedule delay 5 secs, Hold time between two SPFs 10 secs
Number of DCbitless external LSA 0
Number of DoNotAge external LSA 0
Number of areas in this router is 1. 1 normal 0 stub 0 nssa

Configuring a VPI Range (Optional)

Although not necessary for most configurations, you might need to change the default tag virtual path
identifier (VPI) range on the switch if:
•
•
You cannot enter a VPI range on a VP tunnel. On VP tunnels, the VPI is the permanent virtual path
Note
(PVP) number of the tunnel.
ATM Switch Router Software Configuration Guide
16-6
Area BACKBONE(0) (Inactive)
Number of interfaces in this area is 4
Area has no authentication
SPF algorithm executed 2 times
Area ranges are
Link State Update Interval is 00:30:00 and due in 00:14:42
Link State Age Interval is 00:20:00 and due in 00:14:10
Number of DCbitless LSA 0
Number of indication LSA 0
Number of DoNotAge LSA 0
It is an administrative policy to use a VPI value other than 1, the default VPI.
There are a large number of tag virtual channels (TVCs) on an interface.
