enable mpls rsvp-te summary-refresh

enable mpls rsvp-te summary-refresh [{vlan} vlan_name | vlan all]

Description

Enables the sending of summary refresh messages, instead of path messages, to refresh RSVP-TE path state for the specified VLAN interface.

Syntax Description

vlan Specifies that summary refresh messages are to refresh the RSVP-TE path state on one or more VLAN interfaces.
vlan_name Identifies a VLAN interface on which RSVP-TE summary refresh messages are to refresh the RSVP-TE path state.
vlan all Specifies that summary refresh messages are to refresh the RSVP-TE path state on all VLANs that have been added to MPLS.

Default

Disabled.

Usage Guidelines

Enabling summary refresh can improve control plane scalability by refreshing multiple LSPs in a single message. Not all devices support summary refresh. If the switch determines that a peer LSR, connected to a specific interface, does not support summary refresh, the switch reverts to using path messages on that interface. By default, summary refresh is disabled. Specifying the all keyword enables summary refresh on all MPLS-configured VLANs.

Example

The following command enables summary refresh on the specified VLAN:

enable mpls rsvp-te summary-refresh vlan vlan_1
