Figure 6- 147. IPM Route Next Hop window
The IPM Route Next Hop window displays the following fields:
♦ Group – Identifies the IP multicast group from which the multicast packet is being forwarded.
♦ Source – Identifies the source IP address of the multicast packet being forwarded.
♦ Source Mask – Masks all or part of the source IP address.
♦ IfIndex – Identifies the port number of the next-hop.
♦ Next Hop Address – Indicates the IP addresses of the next-hop. This may be identical to the
Group value. However, some ports may have multiple next-hop addresses from a single outgoing
interface.
♦ State – Indicates if the port and next-hop are being used to forward multicast packets. The
possible values are:
◊
Pruned – The port and next hop are not being used to forward multicast packets
◊
Forwarding – The port and the next hop are currently being used to forward multicast
packets.
♦ 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 is not expired. However, if the Hop Status is Pruned, the value indicates the amount of
time remaining before the port and next hop revert to Forwarding.
♦ Protocol – Identifies the routing protocol used to find the next hop. The possible values are:
◊
Other – Indicates that none of the below listed protocols are used to find the next
upstream or parent interface for the next-hop.
◊
Local – Indicates that at manually configured protocol was used to find the next
upstream or parent interface for the next-hop.
◊
Netmgmt – Indicates that the Network Management Protocol was used to find the
next upstream or parent interface for the next-hop. This route is static.
