IPM Routing Table

The IPM Routing Table contains multicast routing informatin of IP packets sent from a specific source to IP multicast groups known to the IPM router.

The IPM Routing Table window displays the following fields:

• Group — Identifies the multicast group IP address.

• Source — Identifies the current device source IP address.

• Source Mask — Masks all or parts of the source IP address.

• Upstream Neighbor — Specifies the next upstream device IP address from which packets to the IP address are received. The value 0.0.0.0 indicates that the value is unknown.

• In IfIndex — Indicates the port number to which multicast packets being sent are received. The value 0 indicates that incoming packets can be received on multiple interfaces.

• Up Time — Indicates the time lapse since the router learned the multicast information.

• Expiry Time — Indicates the time in ticks before the entry expires. A value of 0 indicates that the entry has not expired.

• Protocol — Identifies the type of protocol used to learn the multicast information. The possible values are:

• Other — Indicates that none of the protocols listed below are used to learn multicast forwarding information.

• Local — Indicates that a manually configured protocol is used to learn multicast information.

• Netmgmt — Indicates that the Network Management Protocol is used to learn multicast information.

• DVMRP — Indicates that the Distance Vector Multicast Routing Protocol (DVRP) is used to learn multicast information.

• MOSPF — Indicates that Multicast extended OSPF (MOSPF) is used to learn multicast information.

• PIMSparseDense — Indicates that Protocol Independent Multicast is used to learn multicast information.

• CBT — Indicates that CBT is used to learn multicast information.

• PIM-SM — Indicates that Protocol Independent Multicast-Sparce Mode is used to learned multicast information.

• PIM-DM—Indicates that Protocol Independent Multicast-Dense Mode is used to learned the multicast information.

• IGMP — Indicates that Internet Group Multicast Protocol is used to learn multicast information.

• BGMP — Indicates that the Border Gateway Multicast protocols is used to learn multicast information for the current entry.

• MSDP — Indicates that the Multicast Source Discovery Protocol is used to learn the multicast information.

• Routing Mechanism—Identifies the routing mechanism used to find the next upstream or parent interface which provided the multicast information. The possible values are:

• Other — Indicates that none of the below listed protocols are used to find the next upstream or parent interface of the multicast information.

• Local — Indicates that a manually configured protocol is used to find the next upstream or multicast parent interface information.

• Netmgmt — Indicates that the Network Management Protocol is used to find the next upstream or parent interface of the multicast information. This route is static.

• ICMP — Indicates that the Internet Control Message Protocol is used to find the next upstream or parent interface for the multicast information.

• RIP — Indicates that the Routing Information Protocol is used to find the next upstream or parent interface of the multicast information.

• OSPF — Indicates that the Open First Path First Protocol is used to find the next upstream or parent interface of the multicast information.

• BGP — Indicates that the Border Gateway Protocol is used to find the next upstream or parent interface of the multicast information.

• DVRMP — Indicates that the Internet Control Message Protocol is used to find the next upstream or parent interface of the multicast information.

• Routing Address — Identifies the IP address used to find the upstream or parent interface of the multicast information.

• Route Mask — Masks all or part of the IP addresses used to find the upstream or parent interface of the multicast information.

• Route Type — Indicates if the route was a Unicast or Multicast route. The possible values are:

• Unicast — Indicates that the route was placed in the multicast routing information base (RIB) either instead of or in addition to unicast RIB by a local configuration, for example when running PIM over RIP.

• Multicast — Indicates that the route was explicitly added to the multicast RIB by the routing protocol.
