The enhanced ECMP limit of up to 64 ECMP next hops is also applicable for
Layer 3 VPNs, Layer 2 VPNs, Layer 2 circuits, and VPLS services that resolve
over an MPLS route, because the available ECMP paths in the MPLS route can
also be used by such traffic.
NOTE:
The following FPCs on M320, T640, and T1600 routers only support 16 ECMP next
hops:
■ (M320, T640, and T1600 routers only) Enhanced II FPC1
■ (M320, T640, and T1600 routers only) Enhanced II FPC2
■ (M320 and T640 routers only) Enhanced II FPC3
■ (T640 and T1600 routers only) FPC2
■ (T640 and T1600 routers only) FPC3
If a maximum ECMP next-hop limit of 32 or 64 is configured on an M320, T640, or
T1600 router with any of these FPCs installed, the Packet Forwarding Engines on
these FPCs use only the first 16 ECMP next hops. For Packet Forwarding Engines on
FPCs that support only 16 ECMP next hops, the JUNOS Software generates a system
log message if a maximum ECMP next-hop limit of 32 or 64 is configured. However,
for Packet Forwarding Engines on other FPCs installed on the router, a maximum
configured ECMP limit of 32 or 64 ECMP next hops is applicable.
To view the details of the ECMP next hops, issue the show route command. The
show route summary command also shows the current configuration for the
maximum ECMP limit. To view details of the ECMP LDP paths, issue the traceroute
mpls ldp command.

■ Support for configuring time-based user access—The JUNOS Software enables
you to configure time-based restrictions for user access to log in to a device. This
is useful for restricting the time and duration of user logins for all users belonging
to a login class. You can specify the days of the week when users can log in, the
access start time, and the access end time.
■ To configure user access on specific days of the week, without any restrictions
on the duration of login, include the allowed-days statement only.
[edit system]
login {
class class-name {
allowed-days days-of-the-week;
}
■ To configure user access on all the days of the week for a specific duration,
include the access-start and access-end statements only.
