L2TP Characteristics
A profile can contain the following L2TP characteristic:
MLPPP and PPP Characteristics
A profile can contain one or more of the following MLPPP or PPP characteristics:
566
Configuring a Dynamic Interface from a Profile
sa-validate Enables source address validation
unnumbered Configures IPv6 on this interface without a specific address
virtual-router Specifies a virtual router to which interfaces created by this profile
attach
policy Assigns an L2TP policy list to a profile
aaa-profile Assigns an AAA profile
authentication Requests PAP or CHAP authentication from a PPP peer
authentication virtual router Specifies a virtual router for the authentication
virtual router context
chap challenge length Modifies the length of the CHAP challenge
fragmentation Enables fragmentation on an MLPPP link interface
hash-link-selection Enables use of a hash-based algorithm to select the link on
which the router transmits non-best-effort (high-priority) packets, such as voice
or video, on dynamic MLPPP interfaces
initiate-ip Initiates IPv4 for passive clients
initiate-ipv6 Initiates IPv6 for passive clients
ipcp lockout Terminates an invalid subscriber entry and prevents additional
IPCP negotiations
ipcp netmask Controls the negotiation of the IPCP netmask option 0x90; disabled
indicates do not negotiate, enabled indicates negotiate
keepalive Specifies a keepalive value, in seconds
log Enables packet or state machine logging for any dynamic interfaces that
use the profile
magic-number disable Disables negotiation of the local magic number
magic-number ignore-mismatch Causes the router to ignore a mismatch of the
LCP peer magic number and retain the PPP connection when the peer has not
negotiated an LCP magic number.
max-negotiations Configures the maximum number of LCP, IPCP, or IPv6CP
renegotiation attempts that the router accepts before terminating a PPP session
mru Configures the maximum receive unit size for the interface
multilink enable For MLPPP interfaces only, enables the creation of dynamic
MLPPP interfaces
