26-4874-64 ERX-Tunnel-Group The name of the tunnel group that refers to the CLI created
tunnel-group-name context.(configure router/service vprn
service-id l2tp group tunnel-group-name). Any other RADIUS
returned L2TP parameter is ignored and other required info to
setup the tunnel will have to come from the CLI created context.
Strings above the Limits are treated as a setup failure.
26-6527-46 Alc-Tunnel-Group The tunnel-group-name that refers to the CLI created tunnel-
group-name context.(configure router/service vprn service-
id l2tp group tunnel-group-name). Any other RADIUS
returned L2TP parameter is ignored and other required info to
setup the tunnel will have to come from the CLI created context.
Strings above the Limits are treated as a setup failure.
26-6527-47 Alc-Tunnel-Algorithm Describes how new sessions are assigned (weighted-access,
weighted-random or existing-first) to one of the set of suitable
tunnels that are available or could be made available. A
preconfigured algorithm (configure router/service vprn
service-id l2tp session-assign-method) is used when this
attribute is omitted.
Attribute value existing-first specifies that the first suitable
tunnel is used or set up for the first session and re-used for all
subsequent sessions.
The weighted-access attribute value (session-assign-method
weighted) specifies that the sessions are equally distributed
over the available tunnels; new tunnels are set up until the
maximum number is reached; the distribution aims at an equal
ratio of the actual number of sessions to the maximum number
of sessions. When there are multiple tunnels with an equal
number of sessions (equal weight), LAC selects the first tunnel
from the candidate list.
The weighted-random attribute value enhances the weighted-
access algorithm such that when there are multiple tunnels with
an equal number of sessions (equal weight), LAC randomly
selects a tunnel.
The maximum number of sessions per tunnel is retrieved via
attribute 26-6527-48 Alc-Tunnel-Max-Sessions or set to a
preconfigured value if Alc-Tunnel-Max-Sessions is omitted.
Values outside the limits are treated as a setup failure.
