Enhanced VRF support for Cisco Nexus devices

 
casp1032
 
Starting from CA Spectrum 10.2.1, VRF support for Cisco Nexus devices is enhanced. CA Spectrum now displays the list of VRF available on the devices along with the IP Routing and IP Address table for each VRF. You can now select the specific VRF you want from the VRFs available on the router/device and view the IP Routing/ IP Address table corresponding to the selected VRF.
Virtual Routing and Forwarding technology that allows multiple instances of a routing table to coexist on the same router at the same time. There can be multiple VRFs on the same router. Prior to this release the Interface tab would not populate the IP Addresses of non-default VRFs. Even if the device had multiple VRFs, only the instances belonging to the default VRF would display the IP Addresses. From this release we are polling the IP Address Table, per VRF, mapping the IP Address table and populating data in the
Interfaces
tab >
IP Address
column.
CA Spectrum now displays the list of VRFs available on the router/devices and the routing table for each VRF. You can select the VRF by clicking the Per VRF button and view the corresponding/associated routing table.
Prerequisite!
You have to create/configure the VRF context in the device on the SNMP side, i.e. context mapping needs to be performed as a prerequisite to be able to get the VRF-IP Routing Table.
To view the IP Routing table for a specific VRF, follow these steps:
  1. In the CA Spectrum OneClick >
    Explorer
    View, navigate to
    Virtual Device Manager
    > Cisco Nexus device (which has VDC/VRF) >
    Information
    tab.
  2. Select one of the following: 
    • IP Routing Table
    • IP Address Table

  3. Click
    Per VRF
    The
    Select VRF
    dialog box displays the list of VRFs available on the router/ Cisco Nexus device.
    Select VRF dialog.png
  4. Select the
    VRF
    you wish to view the IP Routing/ IP Address table data, and click
    OK
    .
    The IP Routing/ IP Address table now displays the data specific to the VRF you have selected. 
If there are multiple routes for the same destination in Cisco Nexus device, the IP Routing Table in the Information Tab, does not list all the routes, as the MIB used (IPRoutingTable) populates only one next hop address. This is applicable for default or any other VRF.
