Configuring The Global L2Tp Peer Resynchronization Method - Juniper JUNOSE 11.1.X - BROADBAND ACCESS CONFIGURATION GUIDE 6-4-2010 Configuration Manual

Configuring the Global L2TP Peer Resynchronization Method

You can configure the peer resynchronization method globally, or for L2TP host
profiles or domain map tunnels a host profile or domain map tunnel configuration
takes precedence over the global peer resynchronization configuration.
When you change the peer resynchronization method, the change is not immediately
applied to existing tunnels. Tunnels continue using their current resynchronization
method until the next time the tunnel is reestablished.
Use the l2tp failover-resync command to configure the global L2TP peer
resynchronization method that L2TP failed endpoints use to resynchronize with a
peer non-failed endpoint.
Choose one of the following keywords to specify the peer resynchronization method.
All tunnels in the chassis use the specified method unless it is overridden by an L2TP
host profile configuration or an AAA domain map configuration.
Use the show l2tp command to display the global peer resynchronization
configuration.
host1(config)#l2tp destination profile lac-dest ip address 192.168.20.2
host1(config-l2tp-dest-profile)#remote host lac-host
host1(config-l2tp-dest-host-profile-host)#failover-resync silent-failover
To configure peer resynchronization for an AAA domain map tunnel:
host1(config)#aaa domain-map lac-tunnel
host1(config-domain-map)#tunnel 10
host1(config-domain-map-tunnel)#failover-resync silent-failover
failover-protocol Tunnels use the L2TP failover protocol method. If the peer
non-failed endpoint does not support the L2TP failover protocol, a failover forces
disconnection of all tunnels and their sessions.
failover-protocol-fallback-to-silent-failover Tunnels use the L2TP failover
protocol method; however, if the peer non-failed endpoint does not support the
L2TP failover protocol method, the tunnel falls back to using the silent failover
method.
silent-failover Tunnels use the silent failover method. The tunnels also inform
their peers that they support the failover protocol method for peer failovers.
disable Tunnels do not use any peer resynchronization method for their own
failovers. Tunnels inform their peers that they support the failover protocol
method for peer failovers. A failover forces the disconnection of all tunnels and
sessions.
To configure peer resynchronization for an L2TP host profile or AAA domain
map tunnel:
host1(config)#l2tp failover-resync silent-failover

failover-protocol-fallback-to-silent-failover method:
