Examples: Configuring T3 Interfaces

T3 interfaces can use PPP, Cisco HDLC, or Frame Relay encapsulation.

PPP Encapsulation on a DS3 PIC

[edit]interfaces {t3-0/0/0 {encapsulation ppp;t3-options {no-long-buildout;compatibility-mode larscom;payload-scrambler;}unit 0 {family inet {address 10.0.0.1/32 {destination 10.0.0.2;}}family iso;}}}

Cisco HDLC Encapsulation on a DS3 PIC

[edit]interfaces {t3-0/0/1 {encapsulation cisco-hdlc;t3-options {no-long-buildout;compatibility-mode larscom;payload-scrambler;}unit 0 {family inet {address 10.0.0.1/32 {destination 10.0.0.2;}}family iso;}}}

Configure Frame Relay encapsulation on two routers, where one router is a DTE device and the other is a DCE device:

On DTE Router

[edit]interfaces {t3-1/0/1 {encapsulation frame-relay;t3-options {no-long-buildout;compatibility-mode larscom;payload-scrambler;}unit 1 {dlci 1;family inet {address 10.0.0.1/32 {destination 10.0.0.2;}}family iso;}unit 2 {dlci 2;family inet {address 10.0.0.3/32 {destination 10.0.0.4;}}family iso;}}}

On DCE Router

[edit]interfaces {t3-1/1/1 {dce;encapsulation frame-relay;t3-options {no-long-buildout;compatibility-mode larscom;payload-scrambler;}unit 1 {dlci 1;family inet {address 10.0.0.2/32 {destination 10.0.0.1;}}family iso;}unit 2 {dlci 2;family inet {address 10.0.0.4/32 {destination 10.0.0.3;}}family iso;}}}
