For more information about identifying the port number on a tunnel-server port,
see “Configuring Tunnel-Server Ports and Tunnel-Service Interfaces” on page
221
.
For information about installing tunnel-server modules in the E120 and E320 routers,
see
E120 and E320 Hardware Guide, Chapter 4, Installing Modules .
Interface Specifier
The configuration task examples in this chapter use the format for ERX-7xx models,
ERX-14xx models, and the ERX-310 router to specify a tunnel-server port. (The
format is described in “Numbering Scheme” on page 215
. )
For example, the following command specifies a dedicated tunnel-server port on
port 0 of a tunnel-server module in slot 4.
host1(config)# tunnel-server 4/0
When you configure a tunnel-server port on an E120 router or an E320 router, you
must include the adapter identifier as part of the interface specifier. For example,
the following command specifies a dedicated tunnel-server port on port 0 of an
ES2-S1 Service IOA installed in both the upper and lower bays of slot 3. (When a
full-height IOA is installed in the E120 router or the E320 router, it is identified in
the software by the upper adapter bay 0.)
host1(config)# tunnel-server 3/0/0
For more information about interface types and specifiers on E-series models, see
Interface Types and Specifiers in
JUNOSe Command Reference Guide .
Supported Applications for Dedicated and Shared Tunnel-Server Ports
Dedicated and shared tunnel-server ports provide support for some or all of the
following applications and services, depending on the capabilities of the tunnel-server
module on which the port resides:
■
Distance Vector Multicast Routing Protocol (DVMRP) tunnels, also known as
IP-in-IP tunnels
■
Generic routing encapsulation (GRE) tunnels
■
IPSec (on ISMs only)
■
Layer 2 Tunneling Protocol (L2TP) network server (LNS) support
■
IP packet reassembly for tunnels
■
Network Address Translation (NAT)
NOTE: Support for IP reassembly and NAT services on shared tunnel-server ports
depends on the capabilities of the module on which the shared tunnel-server port
resides.
