multicast-ecmp enable

Use multicast-ecmp enable to enable TRILL multicast Equal Cost Multiple Path (ECMP).

Use undo multicast-ecmp enable to disable TRILL multicast ECMP.

Syntax

multicast-ecmp enable [ p2p-ignore ]

undo multicast-ecmp enable

Default

TRILL multicast ECMP is disabled.

Views

TRILL view

Predefined user roles

network-admin

mdc-admin

Parameters

p2p-ignore: Uses one of the equal-cost routes between the DRB and its neighbor to forward multicast traffic when the pseudonode bypass feature is enabled on the DRB. If you do not specify this keyword, all the equal-cost routes are used to share traffic. To communicate with a third-party device, you can specify this keyword as required.

Usage guidelines

	CAUTION: For multicast traffic to be forwarded correctly, make sure the status of TRILL multicast ECMP is the same across the TRILL network.

When multicast ECMP is disabled, TRILL distribution trees do not use equal-cost routes to share traffic. When multicast ECMP is enabled, TRILL assigns equal-cost routes to multiple TRILL distribution trees to improve load sharing performance.

Examples

# Enable TRILL multicast ECMP.

<Sysname> system-view
[Sysname] trill
[Sysname-trill] multicast-ecmp enable
