MULTICAST COMMANDS
IPV
6 MROUTE
ipv6 mroute
Overview Use this command to inform multicast of the RPF (Reverse Path Forwarding) route
to a given IPv6 multicast source.
Use the no variant of this command to delete a route to an IPv6 multicast source.
Syntax
ipv6 mroute <ipv6-source-address/mask-length> [rip|static]
<rpf-address> [<admin-distance>]
no ipv6 mroute <ipv6-source-address/mask-length> [rip|static]
Mode Global Configuration
Usage notes Typically, when a Layer 3 multicast routing protocol is determining the RPF
(Reverse Path Forwarding) interface for the path to a multicast source, it uses the
unicast IPv6 route table to find the best path to the source. However, in some
networks a deliberate choice is made to send multicast via different paths to those
used for unicast. In this case, the interface via which a multicast stream from a
given source enters a router may not be the same as the interface that connects to
the best unicast route to that source.
This command enables the user to statically configure the switch with “multicast
routes” back to given sources. When performing the RPF check on a stream from a
given IPv6 source, the multicast routing protocol will look at these static entries as
well as looking into the unicast routing table. The route with the lowest
administrative distance - whether a static “multicast route” or a route from the
unicast route table - will be chosen as the RPF route to the source.
Parameter Description
<ipv6-source-
address/mask-length>
A multicast source IPv6 address and mask length, in
hexadecimal notation in the format X.X::X.X/M.
rip RIPng IPv6 unicast routing protocol.
static Specifies a static route.
<rpf-address> X.X::X:X
The closest known address on the IPv6 multicast route
back to the specified source. This host IPv6 address can
be within a directly connected subnet or within a
remote subnet. In the case that the address is in a
remote subnet, a lookup is done from the unicast route
table to find the nexthop address on the path to this
host.
<admin-distance> The administrative distance. Use this to determine
whether the RPF lookup selects the unicast or multicast
route. Lower distances have preference. If the multicast
static route has the same distance as the other RPF
sources, the multicast static route takes precedence. The
default is 0 and the range available is 0-255.
