Monitoring Active IPv6 Multicast Routes

Purpose

Display the active multicast routes.

Action

To display the active multicast routes with admission bandwidth above 10000 bps:

host1#show ipv6 mroute active 10000
Active IP Multicast Routes >=10000 bps
(S, G) uptime d h:m:s[, expires d h:m:s]
[Admission bandwidth: bps]
[QoS bandwidth: bps]
RPF route: addr/mask, incoming interface
neighbor address, owner route-owner
Incoming interface list:
Interface (addr/mask), State/Owner [(RPF IIF)]
Outgoing interface list:
Interface (addr/mask), State/Owner, Uptime/Expires
(52::1, ff3e::1) uptime 0 00:01:07
Admission bandwidth: 47000 bps (adaptive)
QoS bandwidth: 47000 bps (adaptive)
RPF route: 52::/112, incoming interface ATM2/1.17
neighbor 17::2, owner NetmgmtRpf
Incoming interface list:
ATM2/1.17 (fe80::90:1a00:3140:1ff8/128), Accept/MLD (RPF IIF)
Outgoing interface list:
NULL
Counts: 1 (S, G) entries
0 (*, G) entries

To display the summary of active multicast routes:

host1#show ipv6 mroute summary active
Active IP Multicast Routes >=4000 bps
Group Address Source Address  RPF route RPF Iif   #Oifs
--------------- ------------ ----------- --------- -----
232.0.0.1     51.0.0.1      51.0.0.0/24  ATM3/1.17  0
232.0.0.2     51.0.0.1      51.0.0.0/24  ATM3/1.17  0
232.0.0.3     51.0.0.1      51.0.0.0/24  ATM3/1.17  0
Counts: 3 (S, G) entries
0 (*, G) entries

Meaning

Table 57 lists the show ipv6 mroute active and show ipv6 mroute summary active commands output fields.

Table 57: show ipv6 mroute active and show ipv6 mroute summary active Output Fields

Field Name

Field Description

(S,G)

IPv6 addresses of the multicast source and the multicast group

Uptime

Length of time that the (S,G) pair has been active, in days hours:minutes:seconds format

Expires

Length of time for which the (S,G) pair will be active, in days hours:minutes:seconds format

Admission bandwidth

Admission bandwidth (in bps)

QoS bandwidth

QoS bandwidth (in bps)

RPF Route

IPv6 address and prefix of the RPF route

Incoming interface

Type and specifier of the incoming interface for the RPF route

neighbor address

IPv6 address of the neighbor

owner

Owner of the route:

  • Local—route belonging to the local interface
  • Static—Static route
  • Other protocols—Route established by a protocol

Incoming interface list

List of incoming interfaces on the router. Details include:

  • Type of interface and its specifier
  • Action that the interface takes with packets: accept or discard
  • Multicast protocol that owns the interface
  • Time that the interface has been active in this multicast forwarding entry, in days hours:minutes:seconds format
  • Time that the interface will cease to be active in this multicast forwarding entry, in days hours:minutes:seconds format

Outgoing interface list

List of outgoing interfaces on the router. Details include:

  • Type of interface and its specifier
  • Action that the interface takes with packets: Forward or Blocked (intf-adm-limit, join-intf-adm-limit, port-adm-limit, port-limit, port-priority-limit)
  • Protocol running on the interface: PIM or MLD
  • Time that the interface has been active in this multicast forwarding entry, in days hours:minutes:seconds format
  • Time that the interface will cease to be active in this multicast forwarding entry, in days hours:minutes:seconds format

Counts

Numbers of types of source group mappings:

  • (S,G)—Number of (S,G) entries
  • (*,G)—Number of (*,G) entries

Group Address

IP address of the multicast group

Source Address

IP address of the multicast source

RPF Iif

Type and identifier for the incoming interface for the RPF route

#Oifs

Number of outgoing interfaces
