    IP Multicast Reverse Path View

    The reverse path view shows the multicast routing path from a receiver router to the source router.

    The URL action to launch the IP Multicast Reverse Path view only appears after you install the iSPI for IP Multicast and verify that all NNMi and IP Multicast processes are running. For more information, see the iSPI for IP Multicast Installation Guide and Online Help.

    To launch the iSPI for IP Multicast reverse path view:

    1. Navigate to the MVRF Form
      1. From the Workspaces navigation pane, click MPLS-> MPLS L3 VPN Inventory. Alternatively, from the Workspaces navigation pane, click MPLS-> MVPN Inventory. The L3 VPN Inventory view opens in the right pane. Select the MVPN tab.
      2. Click (the Open icon) to view the MVRF form.
    2. From the MVRF form, select the Downstream MDTs Tab. Select the Data MDT. Do not select the Default MDT.
    3. Click the URL for Multicast Reverse Path View from the Analysis Pane
    4. Click (the Refresh icon) to update the reverse path view.

    MPLS Map Symbols

    (See, About Map Symbols and About Status Colors in NNM Online Help: Console Help before you begin with this topic)

    The map views provide you with the graphical representation of the MPLS objects participating on the network. Map symbols are used to represent nodes, interfaces, and MPLS objects such as VRFs, VRF Lites, MVRFs, Hub VRF, and Hub MVRFs, The lines between the nodes and interfaces represent the connection or relationship between these objects.

    The NNM iSPI for MPLS uses NNMi shapes for the nodes and interfaces. The NNM iSPI for MPLS uses the same symbols to represent both, a VRF or a VRF-Lite on the map. The NNM iSPI for MPLS uses the NNMi status colors to represent the status of the MPLS object. For more information, see NNMi Help, About Status Colors. The icons used to show the MPLS objects are as follows:

    Icons Used By MPLS
    Icons Meaning
    Used in maps to represent a VRF.
    Used in maps to represent a Hub VRF.
    Used in maps to represent a VRF-Lite.
    Used in maps to represent an MVRF.
    Used in maps to represent a Hub MVRF.
    Used in map view to represent a CE node.

    Used in L3 VPN to show:

    • A full mesh L3 VPN topology on the network.
    • A PE interface connected to an unknown CE interface. The CE interface on the node is indicated on the map by a cloud symbol.
    • Multiple PE interfaces connected to one CE interface. This path is detected by the Hot Standby Router Protocol (HSRP) link connectivity. This HSRP connection is indicated on the map by a cloud symbol.
    • Multiple CE interfaces connected to one PE interface. This path is connected by a switch. This is indicated on the map by a cloud symbol.

    Used in Inter-provider VPN to show:

    • Third-party VPN clouds participating in the Inter-Provider VPN

    Used in L2 VPN to show:

    • A full mesh L2 VPN on the network
    • A service object connected to an unknown CE interface. The CE interface on the node is indicated on the map by a cloud symbol.

     

    Represents the service centric object associated with a VPLS. For example, VPLS_<vc id>@hostname
    Represents the service centric object associated with a VPWS. <vpws_groupname>@<hostname>
    Connector that represents a CE-VRF-Lite or PE-VRF-Lite connection.
    Represents a Pseudo Wire. The color of the selected Pseudo Wire is the status color.
    Represents collective Pseudo Wires grouped as one. You can click this symbol to view individual Pseudo Wires in the Analysis Pane. The color of the selected Pseudo Wire is the status color.
    Represents TE Tunnel.
    Shapes Used By MPLS
    Icons Meaning
    Used to show the Full Mesh L3 VPN. This shape is superimposed with the cloud icon.

    Used to show an unknown CE node. When the shape is superimposed with the cloud icon, it represents the following:

    • A PE interface connected to an unknown CE interface. The CE interface on the node is indicated on the map by a cloud symbol.
    • Multiple PE interfaces connected to one CE interface. This path is detected by the Hot Standby Router Protocol (HSRP) link connectivity. This HSRP connection is indicated on the map by a cloud symbol.
    • Multiple CE interfaces connected to one PE interface. This path is connected by a switch. This is indicated on the map by a cloud symbol.
    Used to represent a VRF. In a map view, this symbol is superimposed with the 'VRF' or 'VRF Lite' symbol. The color of the selected VRF is the status color.
    Used to represent a switch. The color of the selected switch is the status color.
    Used to represent third-party VPN provider in an Inter-Provider VPN network. This shape is superimposed with the cloud icon.
