Configuring the VRF timeout value

Use this procedure to configure the VRF timeout value. The timeout value ages out the sender when there is no multicast stream on the VRF. The default is 210 seconds.

Note

Note

You can use this procedure for Layer 3 VSN with IP Multicast over Fabric Connect services and IP Multicast over Fabric Connect for IP Shortcuts.

Before you begin

  • You must configure the required SPBM and IS-IS infrastructure, which includes the creation of SPBM B-VLANs.

  • You must create the C-VLANs and add slots/ports.

  • You must enable IP Multicast over Fabric Connect globally.

Procedure

  1. Enter VRF Router Configuration mode for a specific VRF context:

    enable

    configure terminal

    router vrf WORD<1-16>

  2. Configure the timeout value on the VRF:

    mvpn fwd-cache-timeout(seconds) <10–432000>

  3. Optional: Configure the timeout value to the default value of 210 seconds:

    no mvpn fwd-cache-timeout

    default mvpn fwd-cache-timeout(seconds)

Example

Configure the timeout value on the VRF to 500 seconds:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#router vrf green
Switch:1(router-vrf)#mvpn fwd-cache-timeout(seconds) 500
