lowing more efficient use of network resources and preventing traffic congestion. With this
feature, multicast traffic is split across the equal cost multipath based on either its source
address or its source and group address.
Fig. 11.3 Multicast Equal Cost Multipath (ECMP)
ECMP load splitting has two options for next hop decision:
• srcip selects next hop based on source address.
• srcgrpip selects next hop based on both source and group address.
To enable ECMP load splitting for IPv6, use the following command.
Command
Mode
Description
ipv6 multicast multipath [srcip |
srcgrpip]
Global
Enables IPv6 ECMP load splitting.
srcip: source address (default)
srcgrpip: source and group address
no ip multicast multipath
Disables ECMP load splitting.
To disable ECMP load splitting for IPv6, use the following command.
Command
Mode
Description
no ipv6 multicast multipath
Global
Disables IPv6 ECMP load splitting.
11.3.1.3 MRIB Entry Limit
You can limit the maximum number of multicast routing entries in the multicast routing ta-
ble in the multicast routing information base (MRIB), and then the system generates an
error message when the number of the entries exceeds the limit. If the warning threshold
is specified, the system generates a warning message when the number of the entries
exceeds the threshold.
To specify the maximum number of multicast routing entries, use the following command.
Command
Mode
Description
ipv6 multicast route-limit LIMIT
[THRESHOLD]
Global
Specifies the limit of the maximum number of multicast
routing entries.
