Configuring IPv6 Multicast
To display the MRIB table, use the show command described in the following example. All entries are
created by various clients of MRIB, such as, MLD, PIM and MFIB. The flags on each entry or interface,
serve as communication mechanism between various clients of MRIB.
Router# show ipv6 mrib route FF0E::E0:1:1:1
IP Multicast Routing Information Base
Entry flags: L - Domain-Local Source, E - External Source to the Domain,
C - Directly-Connected Check, S - Signal, IA - Inherit Accept, D - Drop
Interface flags: F - Forward, A - Accept, IC - Internal Copy,
NS - Negate Signal, DP - Don't Preserve, SP - Signal Present,
II - Internal Interest, ID - Internal Disinterest, LI - Local
Interest,
LD - Local Disinterest

FastEthernet4/10 Flags: F NS
To display the count of the number of routes in the Multicast RIB, use the show command described in
the following example.
Router# show ipv6 mrib route summary
MRIB Route-DB Summary
No. of (*,G) routes = 53
No. of (S,G) routes = 1
No. of Route x Interfaces (RxI) = 24
To display information about the various MRIB clients, use the show command described in the
following example.
Router# show ipv6 mrib client
IP MRIB client-connections
igmp:110 (connection id 0)
pim:162 (connection id 1)
mfib ipv6:3 (connection id 2)
To display information about the IPv6 Multicast Forwarding Information Base, in terms of forwarding
entries and interfaces, use the show command described in the following example.
Router# show ipv6 mfib FF0E::E0:1:1:1
IP Multicast Forwarding Information Base
Entry Flags: C - Directly Connected, S - Signal, IA - Inherit A flag,
AR - Activity Required, D - Drop
Forwarding Counts: Pkt Count/Pkts per second/Avg Pkt Size/Kbits per second
Other counts: Total/RPF failed/Other drops
Interface Flags: A - Accept, F - Forward, NS - Negate Signalling
IC - Internal Copy, NP - Not platform switched
SP - Signal Present
Interface Counts: FS Pkt Count/PS Pkt Count
(*,FF0E::E0:1:1:1) Flags: C
Forwarding: 0/0/0/0, Other: 0/0/0
