Configuring the Global L2TP Peer Resynchronization Method

390
silent-failover—The tunnel uses the silent failover method. The tunnel also informs
its peer that it supports the failover protocol method for the peer's failovers.
disable—The tunnel does not use any peer resynchronization method for its own
failovers, The tunnel informs its peer that it supports the failover protocol method for
the peer's failovers. A failover forces the disconnection of the tunnel and all of its
sessions.
not-configured—Peer resynchronization is not configured for L2TP host profiles and
AAA domain map tunnels. L2TP uses the global failover method.
By default, peer resynchronization is not configured at the L2TP profile-level or the domain
map-level—therefore, the global configuration is used. This is different than using the
disable keyword, which specifies that no peer synchronization method is used.
Use the show l2tp destination profile command to display a host profile's peer
resynchronization configuration and the show aaa domain-map command to display a
domain map's configuration.
To configure peer resynchronization for an L2TP host profile:
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
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.
