Configuring RSMLT on a VLAN

Configure RSMLT on a VLAN to exchange Layer 3 information between peer nodes in a switch cluster. This configuration applies to both IPv4 and IPv6.

Before you begin

  • Enable an IP routing protocol on VLAN Layer 3 interfaces.

  • Ensure VLANs with Layer 3 interfaces participate in Split MultiLink Trunking (SMLT).

About this task

The VLAN can be either IPv4 or IPv6, or both. RSMLT configuration on a VLAN simultaneously affects both IPv4 and IPv6.

Procedure

  1. In the navigation tree, expand the following folders: Configuration > VLAN.
  2. Click VLANs.
  3. Click the Basic tab.
  4. Select a VLAN.
  5. Click IP.
  6. Click the RSMLT tab.
  7. Select Enable.
  8. In the HoldDownTimer field, type a hold-down timer value.
  9. In the HoldUpTimer field, type a holdup timer value.
  10. Click Apply.

RSMLT field descriptions

Use the data in the following table to use the RSMLT tab.

Name

Description

Enable

Enables RSMLT. The default is disabled.

HoldDownTimer

Defines how long the recovering or restarting system remains in a non-Layer 3 forwarding mode for the peer router MAC address.

The range of this value is from 0 to 3600 seconds. The default is 60.

If you disable RSMLT on a VLAN, non default values for this field do not save across restarts.

HoldUpTimer

Defines how long the RSMLT system maintains forwarding for its peer. The value is a range from 0 to 3600 seconds or 9999. 9999 means infinity. The default is 1800.

If you disable RSMLT on a VLAN, non default values for this field do not save across restarts.
