Example: Enabling ECMP Multicast Load Splitting Based on Source Group and Next-Hop Address
The following example shows how to enable ECMP multicast load splitting on a router based on source,
group, and next-hop address using the next-hop-based S-G-hash algorithm:
switch(config)# ip multicast multipath s-g-hash next-hop-based
Example: Enabling ECMP Multicast Load Splitting Based on Source Group and Next-Hop Address
Command or Action
Repeat Steps 1 through 3 on all the routers in a
redundant topology.
end
Example:
switch(config)# end
show ip rpf source-address [group-address]
Example:
switch# show ip rpf 10.1.1.2
show ip route ip-address
Example:
switch# show ip route 10.1.1.2
Cisco Nexus 7000 Series NX-OS Multicast Routing Configuration Guide
Purpose
Be sure to enable the ip multicast
Note
multipath command on the router
that is supposed to be the receiver
for traffic from more than one
incoming interfaces, which is
opposite to unicast routing. From the
perspective of unicast, multicast is
active on the sending router
connecting to more than one
outgoing interfaces.
--
Exits global configuration mode and returns to
privileged EXEC mode.
(Optional) Displays the information that IP
multicast routing uses to perform the RPF
check.
• Use this command to verify RPF selection
so as to ensure that IP multicast traffic is
being properly load split.
(Optional) Displays the current state of the IP
routing table.
• Use this command to verify that there
multiple paths available to a source or RP
for ECMP multicast load splitting.
• For the ip-address argument, enter the IP
address of a source to validate that there
are multiple paths available to the source
(for shortest path trees) or the IP address
of an RP to validate that there are multiple
paths available to the RP (for shared trees).
