Table 215 describes the significant fields shown in the displays.
Table 215 show ipv6 neighbors Field Descriptions
|
|
IPv6 Address |
IPv6 address of neighbor or interface. |
Age |
Time (in minutes) since the address was confirmed to be reachable. A hyphen (-) indicates a static entry. |
Link-layer Addr |
MAC address. If the address is unknown, a hyphen (-) is displayed. |
State |
The state of the neighbor cache entry. Following are the states for dynamic entries in the IPv6 neighbor discovery cache: • INCMP (Incomplete)—Address resolution is being performed on the entry. A neighbor solicitation message has been sent to the solicited-node multicast address of the target, but the corresponding neighbor advertisement message has not yet been received. • REACH (Reachable)—Positive confirmation was received within the last ReachableTime milliseconds that the forward path to the neighbor was functioning properly. While in REACH state, the device takes no special action as packets are sent. • STALE—More than ReachableTime milliseconds have elapsed since the last positive confirmation was received that the forward path was functioning properly. While in STALE state, the device takes no action until a packet is sent. • DELAY—More than ReachableTime milliseconds have elapsed since the last positive confirmation was received that the forward path was functioning properly. A packet was sent within the last DELAY_FIRST_PROBE_TIME seconds. If no reachability confirmation is received within DELAY_FIRST_PROBE_TIME seconds of entering the DELAY state, send a neighbor solicitation message and change the state to PROBE. • PROBE—A reachability confirmation is actively sought by resending neighbor solicitation messages every RetransTimer milliseconds until a reachability confirmation is received. • ????—Unknown state. Following are the possible states for static entries in the IPv6 neighbor discovery cache: • INCMP (Incomplete)—The interface for this entry is down. • REACH (Reachable)—The interface for this entry is up. Note Reachability detection is not applied to static entries in the IPv6 neighbor discovery cache; therefore, the descriptions for the INCMP (Incomplete) and REACH (Reachable) states are different for dynamic and static cache entries. |
Interface |
Interface from which the address was reachable. |
The following is sample output from the show ipv6 neighbors command with the statistics keyword:
Router# show ipv6 neighbor statistics
Entries 2, High-water 2, Gleaned 1, Scavenged 0
INCMP 0 REACH 0 STALE 2 GLEAN 0 DELAY 0 PROBE 0
Requested 1, timeouts 0, resolved 1, failed 0
In-progress 0, High-water 1, Throttled 0, Data discards 0
Requested 3, timeouts 0, resolved 3, failed 0
Table 216 describes the significant fields shown in this display:
Table 216 show ipv6 neighbors statistics Field Descriptions
|
|
Entries |
Total number of ND neighbor entries in the ND cache. |
High-Water |
Maximum amount (so far) of ND neighbor entries in ND cache. |

Scavenged |
Number of stale ND neighbor entries that have timed out and been removed from the cache. |
Entry States1 |
Number of ND neighbor entries in each state. |
Resolutions (INCMP) |
Statistics for neighbor resolutions attempted in INCMP state1 (that is, resolutions prompted by a data packet). Details about the resolutions attempted in INCMP state are follows: • Requested—Total number of resolutions requested. • Timeouts—Number of timeouts during resolutions. • Resolved—Number of successful resolutions. • Failed—Number of unsuccessful resolutions. • In-progress—Number of resolutions in progress. • High-water—Maximum number (so far) of resolutions in progress. • Throttled—Number of times resolution request was ignored due to maximum number of resolutions in progress limit. • Data discards—Number of data packets discarded that are awaiting neighbor resolution. |
Resolutions (PROBE) |
Statistics for neighbor resolutions attempted in PROBE state (that is, re-resolutions of existing entries prompted by a data packet): • Requested—Total number of resolutions requested. • Timeouts—Number of timeouts during resolutions. • Resolved—Number of successful resolutions. • Failed—Number of unsuccessful resolutions. |

Usage Guidelines
Use the show ipv6 pim bsr command to display details of the BSR election-state machine, C-RP advertisement state machine, and the C-RP cache. Information on the C-RP cache is displayed only on the elected BSR router, and information on the C-RP state machine is displayed only on a router configured as a C-RP.
Examples
The following example displays BSM election information:
Router# show ipv6 pim bsr election
Scope Range List: ff00::/8
This system is the Bootstrap Router (BSR)
Uptime: 00:11:55, BSR Priority: 0, Hash mask length: 126
RPF: FE80::A8BB:CCFF:FE03:C400,Ethernet0/0
This system is candidate BSR
Candidate BSR address: 60::1:1:4, priority: 0, hash mask length: 126
Table 243 describes the significant fields shown in the display.
Table 244 show ipv6 pim bsr election Field Descriptions
|
|
Scope Range List |
Scope to which this BSR information applies. |
This system is the Bootstrap Router (BSR) |
Indicates this router is the BSR and provides information on the parameters associated with it. |
BS Timer |
On the elected BSR, the BS timer shows the time in which the next BSM will be originated. On all other routers in the domain, the BS timer shows the time at which the elected BSR expires. |
This system is candidate BSR |
Indicates this router is the candidate BSR and provides information on the parameters associated with it. |
The following example displays information that has been learned from various C-RPs at the BSR. In this example, two candidate RPs have sent advertisements for the FF00::/8 or the default IPv6 multicast range:
Router# show ipv6 pim bsr rp-cache
Group(s) FF00::/8, RP count 2
Priority 192, Holdtime 150
Uptime: 00:12:36, expires: 00:01:55
Priority 192, Holdtime 150
Uptime: 00:12:36, expires: 00:01:5
The following example displays information about the C-RP. This RP has been configured without a specific scope value, so the RP will send C-RP advertisements to all BSRs about which it has learned through BSMs it has received.
Router# show ipv6 pim bsr candidate-rp
All Learnt Scoped Zones, Priority 192, Holdtime 150
Advertisement interval 60 seconds

|
RP |
Address of the RP router if the protocol is sparse mode or bidir. |
Protocol |
Protocol used: sparse mode (SM), Source Specific Multicast (SSM), link-local (LL), or NOROUTE (NO). LL is used for the link-local scoped IPv6 address range (ff[0-f]2::/16). LL is treated as a separate protocol type, because packets received with these destination addresses are not forwarded, but the router might need to receive and process them. NOROUTE or NO is used for the reserved and node-local scoped IPv6 address range (ff[0-f][0-1]::/16). These addresses are nonroutable, and the router does not need to process them. |
Groups |
How many groups are present in the topology table from this range. |
Info source |
Mappings learned from a specific source; in this case, static configuration. |
Uptime |
The uptime for the group mapping displayed. |

15.1(4)M |
The vrf vrf-name keyword and argument were added. |
Usage Guidelines
This command shows the PIM topology table for a given group—(*, G), (S, G), and (S, G) Rendezvous Point Tree (RPT)— as internally stored in a PIM topology table. The PIM topology table may have various entries for a given group, each with its own interface list. The resulting forwarding state is maintained in the Multicast Routing Information Base (MRIB) table, which shows which interface the data packet should be accepted on and which interfaces the data packet should be forwarded to for a given (S, G) entry. Additionally, the Multicast Forwarding Information Base (MFIB) table is used during forwarding to decide on per-packet forwarding actions.
The route-count keyword shows the count of all entries, including link-local entries.
PIM communicates the contents of these entries through the MRIB, which is an intermediary for communication between multicast routing protocols (such as PIM), local membership protocols (such as Multicast Listener Discovery [MLD]), and the multicast forwarding engine of the system.
For example, an interface is added to the (*, G) entry in PIM topology table upon receipt of an MLD report or PIM (*, G) join message. Similarly, an interface is added to the (S, G) entry upon receipt of the MLD INCLUDE report for the S and G or PIM (S, G) join message. Then PIM installs an (S, G) entry in the MRIB with the immediate olist (from (S, G)) and the inherited olist (from (*, G)). Therefore, the proper forwarding state for a given entry (S, G) can be seen only in the MRIB or the MFIB, not in the PIM topology table.
Examples
The following is sample output from the show ipv6 pim topology command:
Router# show ipv6 pim topology

Table 251 describes the significant fields shown in the display.
Table 251 show ipv6 pim topology Field Descriptions
|
|
Entry flags: KAT |
The keepalive timer (KAT) associated with a source is used to keep track of two intervals while the source is alive. When a source first becomes active, the first-hop router sets the keepalive timer to 3 minutes and 30 seconds, during which time it does not probe to see if the source is alive. Once this timer expires, the router enters the probe interval and resets the timer to 65 seconds, during which time the router assumes the source is alive and starts probing to determine if it actually is. If the router determines that the source is alive, the router exits the probe interval and resets the keepalive timer to 3 minutes and 30 seconds. If the source is not alive, the entry is deleted at the end of the probe interval. |
AA, PA |
The assume alive (AA) and probe alive (PA) flags are set when the router is in the probe interval for a particular source. |
RR |
The register received (RR) flag is set on the (S, G) entries on the Route Processor (RP) as long as the RP receives registers from the source Designated Router (DR), which keeps the source state alive on the RP. |
SR |
The sending registers (SR) flag is set on the (S, G) entries on the DR as long as it sends registers to the RP. |
