Overriding All Endpoint Discriminators

NOTE: We strongly recommend that you use this feature only with the support of
JTAC.
You can also configure the router to ignore the value of all endpoint discriminators
when it selects a SM and to use only the bundled group identifier that you assigned
by issuing the bundled-group-overrides-mlppp-ed command.
Issuing the bundled-group-id and bundled-group-id-overrides-mlppp-ed commands
together forces the router to place the bundled sessions on the same SM when a PPP
client incorrectly specifies different endpoint discriminators for links in the same
bundle.

Enabling Tunnel Switching

L2TP tunnel switching allows you to switch packets between one session terminating
at an L2TP LNS and another session originating at an L2TP LAC. What distinguishes
a tunnel-switched LAC from a conventional one is that there are two interface
columns: one for the incoming session (LNS) and one for the outgoing session (LAC).
The router forwards traffic from the incoming session to the outgoing session and
vice versa.
You can select tunnel switching on a per-chassis basis. By default, tunnel switching
is disabled. This preserves current behavior and prevents inadvertent attempts to
switch tunnels.
NOTE: Each individual L2TP session involved in tunnel switching is counted toward
the maximum number of sessions supported on an E Series router.
