Juniper JUNOSE 11.2.X MULTICAST ROUTING, Configuration Manual

Page: 234 / 256

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 or 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
or 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.
For a list of applications and services that dedicated and shared tunnel-server modules
support on ERX7xx models, ERX14xx models, and the ERX310 outer, see
ERX Module
Guide, Appendix A, Module Protocol Support .
For a list of applications and services that dedicated tunnel-server modules support on
the E120 and E320 routers, see
E120 and E320 Module Guide, Appendix A, IOA Protocol
Support .
Redundancy and Interface Distribution of Tunnel-Service Interfaces
The redundancy and distribution mechanisms supported for tunnel-service ports
configured on ISMs differ from those supported for SMs, the ES2-S1 Service IOA, and
shared tunnel-server ports.
