View Multicast Next-Hop Information

View all multicast next-hop information.

This tab shows information about the next hops used by outgoing interfaces to route IP multicast datagrams. Each entry is one in a list of next hops on outgoing interfaces for particular sources that send to a particular multicast group address.

About this task

You can view the multicast routes for a Layer 3 Virtual Services Network (VSN) the same way you view the Global Router except that you must first launch the appropriate VRF context.

Procedure

In the navigation pane, expand Configuration > IP.
Select Multicast.
Select the Next Hops tab.

Next Hops Field Descriptions

Use the data in the following table to use the Next Hops tab.


Name	Description
Group	Displays the IP multicast group for this entry that specifies a next hop on an outgoing interface.
Source	Displays the network address that, when combined with the corresponding next hop SourceMask value, identifies the source for this entry that specifies a next hop on an outgoing interface.
SourceMask	Displays the network mask that, when combined with the corresponding next hop Source value, identifies the source for this entry that specifies a next hop on an outgoing interface.
ReceiverPort	Displays the receiver port for this next hop.
OutInterface	Displays the interface slot and portnumber or VLAN ID for the outgoing interface for this next hop.
Address	Displays the address of the next hop specific to this entry. For most interfaces, it is identical to the next-hop group. Non Broadcast Multiple Access (NBMA) interfaces, however, can use multiple next hop addresses out of a single outgoing interface.
State	Displays whether the outgoing interface and next hop represented by this entry currently forward IP datagrams. A value of forwarding indicates the information is currently used; pruned indicates it is not used.
UpTime	Displays the up time for this entry.
ExpiryTime	Displays the minimum amount of time that remains before this entry ages out. The value 0 indicates that the entry is not subject to aging.
ClosestMemberHops	Displays the minimum number of hops between this router and members of the IP multicast group reached through the next hop on this outgoing interface. IP multicast datagrams for the group that use a time-to-live less than this number of hops are not forwarded to the next hop.
Protocol	Displays the protocol as one of the following: other(1): none of the following local(2): manually configured netmgmt(3): configured by a network management protocol pimSparseMode(8): PIM-SMv2 igmpOnly(10) pimSsmMode(11) spb
Pkts	Displays the number of next hop packets.
