IPv6 Multicast: Static Multicast Routing for IPv6
IPv6 static multicast routes, or mroutes, share the same database as IPv6 static routes and are implemented by extending static route support for reverse path forwarding (RPF) checks.
Finding Feature Information
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

Information About IPv6 Static Mroutes
IPv6 static mroutes behave much in the same way as IPv4 static mroutes used to influence the RPF check. IPv6 static mroutes share the same database as IPv6 static routes and are implemented by extending static route support for RPF checks. Static mroutes support equal-cost multipath mroutes, and they also support unicast-only static routes.
How to Configure IPv6 Static Multicast Routes
Configuring Static Mroutes
Static multicast routes (mroutes) in IPv6 can be implemented as an extension of IPv6 static routes. You can configure your device to use a static route for unicast routing only, to use a static multicast route for multicast RPF selection only, or to use a static route for both unicast routing and multicast RPF selection.
DETAILED STEPS
Configuration Examples for IPv6 Static Multicast Routes
Example: Configuring Static Mroutes
Using the show ipv6 mroute command allows you to verify that multicast IPv6 data is flowing:
Device# show ipv6 mroute ff07::1
Multicast Routing Table
Flags:D - Dense, S - Sparse, B - Bidir Group, s - SSM Group,
C - Connected, L - Local, I - Received Source Specific Host Report,
P - Pruned, R - RP-bit set, F - Register flag, T - SPT-bit set,
J - Join SPT
Timers:Uptime/Expires
Interface state:Interface, State
(*, FF07::1), 00:04:45/00:02:47, RP 2001:DB8:6::6, flags:S
Incoming interface:Tunnel5
RPF nbr:6:6:6::6
Outgoing interface list:
POS4/0, Forward, 00:04:45/00:02:47
(2001:DB8:999::99, FF07::1), 00:02:06/00:01:23, flags:SFT
Incoming interface:POS1/0
RPF nbr:2001:DB8:999::99
Outgoing interface list:
POS4/0, Forward, 00:02:06/00:03:27
The following sample output displays information from the show ipv6 mroute active command:
Device# show ipv6 mroute active
Active IPv6 Multicast Sources - sending >= 4 kbps
Group:FF05::1
Source:2001:DB8:1:1:1
Rate:11 pps/8 kbps(1sec), 8 kbps(last 8 sec)
The following example displays RPF information for the unicast host with the IPv6 address of 2001:DB8:1:1:2:
Device# show ipv6 rpf 2001:DB8:1:1:2
RPF information for 2001:DB8:1:1:2
RPF interface:Ethernet3/2
RPF neighbor:FE80::40:1:3
RPF route/mask:20::/64
RPF type:Unicast
RPF recursion count:0
Metric preference:110
Metric:30
