enable mpls rsvp-te summary-refresh
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
History
This command was first available in ExtremeXOS 11.6.
Platform Availability
