peer

Configures the L2TPv3 tunnel‘s peers. At least one peer must be specified.

Supported on the following devices:

Syntax

peer <1-2> {hostname|ip-address|ipsec-secure|router-id|udp}
peer <1-2> {hostname [<HOSTNAME>|any]} {ipsec-secure|router-id|udp}
peer <1-2> {ip-address <IP>} {hostname|ipsec-secure|router-id|udp}
peer <1-2> {ipsec-secure} {gw [<IP>|<WORD>]}
peer <1-2> {router-id [<IP>|<WORD>|any]} {ipsec-secure|udp}
peer <1-2> {udp} {ipsec-secure|port <1-65535>}

Parameters

peer <1-2> {hostname [<HOSTNAME>|any]} {ipsec-secure|router-id|udp}

peer <1-2>
Configures the tunnel‘s peer ID
  • <1-2> – Specify the ID from 1 - 2. The peer ID identifies the primary (ID 1) secondary (ID 2) peers. The L2TPv3 tunnel is established with the primary peer. The secondary peer is used for tunnel failover. If the peer is not specified, tunnel establishment does not occur.
Note: At any time the tunnel is established with only one peer, unless fast-failover support is configured on the L2TPv3 tunnel. For more information, see fast-failover.

hostname [<HOSTNAME>|any]

Optional. Configures the peers‘ hostname. The hostname options are:

  • <HOSTNAME> – Specifies the hostname as FQDN (Fully Qualified Domain Name) or partial DN or any other name

  • any – Peer name is not specified. If the hostname is ‘any‘ this tunnel is considered as responder only and will allow incoming connection from any host.

ipsec-secure {gw [<IP>|<WORD>]}

After specifying the peer hostname, optionally specify the IPSec settings:

  • ipsec-secure – Optional. Enables auto IPSec on the L2TPv3 tunnel

      • <IP> – Configures IPSec gateway‘s IP address

      • <WORD> – Configures IPSec gateway‘s hostname

    • any – Peer router ID is not specified. This allows incoming connection from any router ID.
