IP Router Configuration
Router Configuration Guide 147
Parameters action — Specifies the Action to be taken when a tunnel or peer has been in the blacklist for the
max-period of time.
Values remove-from-blacklist — The peer or tunnel in the blacklist will
be removed completely from the blacklist and made eligible for
the selection process once the max-time expires. In this mode of
operation, multiple new sessions can be mapped into the same,
newly released tunnel from the blacklist. The first such session
will try to setup the tunnel, while the other will be buffered until
the tunnel establishment process is completed. In case that the
tunnel remains unavailable, it will be placed in the blacklist again.
Consequently all new sessions will have be renegotiated over an
alternate tunnel.
try-one-session — Once the max-time expired, the peer or tunnel
in the blacklist is made available for selection only to a single new
session request. Only upon successful tunnel establishment will
the incoming new sessions be eligible to be mapped into this
tunnel. This behavior will avoid session establishment delays in
case that the tunnel just removed from the blacklist is still
unavailable.
peer-address-change-policy
Syntax peer-address-change-policy {accept | ignore | reject}
Context config>router>l2tp
Description This command specifies what to do in case the system receives a L2TP response from another address
than the one the request was sent to.
Parameters accept — Specifies that this system accepts any source IP address change of received L2TP
control messages related to a locally originated tunnel in the state waitReply and rejects any
peer address change for other tunnels; in case the new peer IP address is accepted, it is learned
and used as destination address in subsequent L2TP messages.
ignore — Specifies that this system ignores any source IP address change of received L2TP
control messages, does not learn any new peer IP address and does not change the destination
address in subsequent L2TP messages.
reject — Specifies that this system rejects any source IP address change of received L2TP control
messages and drops those messages.
