# l2tp tunnel default-receive-window

#### Syntax

l2tp tunnel default-receive-window receiveWindowSize

no l2tp tunnel default-receive-window

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Configures the default L2TP receive window size (RWS) for a tunnel on both the LAC and the LNS. The RWS is the number of packets that the peer can transmit without receiving an acknowledgment from the router. This command affects only those tunnels configured on the router after the command is issued; it has no effect on previously configured tunnels. The no version restores the default behavior, in which the router chooses the default RWS.

#### Options

- receiveWindowSize—Default receive window size, in packets; currently, the only supported value is 4

#### Mode

Global Configuration
