Tag Archives: Frame Relay

Let’s assume that we have a Frame Relay topology like in the picture below. We want to have full IP connectivity between our ‘labnario’ routers. To demonstrate, how to configure different types of Frame Relay interface, I will use:

• physical serial interface on labnario1 router
• logical point-to-point interface on labnario2 router
• logical point-to-multipoint interface on labnario3 router.

Let’s start with labnario1 configuration.

<labnario1>system-view 
[labnario1]interface Serial0/0/0
[labnario1-Serial0/0/0] link-protocol fr
[labnario1-Serial0/0/0] fr map ip 123.100.1.2 102 broadcast
[labnario1-Serial0/0/0] fr map ip 123.100.1.3 103 broadcast
[labnario1-Serial0/0/0] ip address 123.100.1.1 255.255.255.0
