Early Field Trial Features
Increased Number of L2TP Tunnels per Chassis on E120 and E320 Routers
with SRP-320 and ES2 4G LM
The number of L2TP tunnels per chassis on E120 and E320 routers with an
SRP-320 module and an ES2 4G LM has increased from 16,000 to 32,000
Change in existing behavior
: New system maximums as described here.
Early Field Trial Features
The features described in this section are present in the code but have not yet been
fully qualified by Juniper Networks. These features are available only for field test
purposes in this release. If you use any of these features before they have been fully
qualified, it is your responsibility to ensure that the feature operates correctly in
your targeted configuration.
DHCP
Support for DHCP External Server, DHCP Local Server, DHCP Relay, and DHCP
Relay Proxy on POS Access Interfaces
The following packet over SONET (POS) module combinations on E Series
routers now support configuration of the DHCP external server, DHCP local
server, DHCP relay, and DHCP relay proxy applications, alone or in
combination, when the POS module is the access interface:
POS module combinations on the E120 router and the E320 router:
ES2 4G LM with ES2-S1 OC12-2 STM4 POS IOA
ES2 4G LM with ES2-S1 OC48 STM16 POS IOA
POS module combinations on ERX14xx models, ERX7xx models, and the
ERX310 router:
OCx/STMx POS line module with OC3-4 I/O module
OCx/STMx POS line modules with OC12/STM4 I/O module
OC48 line module with OC48 FRAME APS I/O module
In the current release, this feature is available for early field test purposes only.
You can configure DHCP external server, DHCP local server, DHCP relay, and
DHCP relay proxy on these POS modules in either a virtual router (VR) or a VPN
routing and forwarding instance (VRF).
CAUTION:
On E120 and E320 routers with an SRP-320 module, scaling the L2TP
tunnel to more than 16,000 is not supported if the chassis has an ES2 10G LM.
The ES2 10G LM may reset if the L2TP tunnel is scaled to more than 16,000.
