Inter-PSD Forwarding Overview
Inter-PSD forwarding enables PSDs on the JCS1200 platform to communicate on a peer-to-peer basis without requiring external links. Previously, PSDs could communicate with each other only through an external link.
Inter-PSD forwarding is achieved by using tunnel PICs that reside on the PSD. Each PSD you configure for inter-PSD forwarding must have a tunnel PIC available to the PSD. The PSDs communicate over logical interfaces configured on the tunnel PICs. Multiple logical interfaces can be configured on each tunnel PIC, allowing the PSD to communicate with multiple PSDs over the same tunnel PIC.
Currently, only Frame Relay encapsulation is supported for inter-PSD forwarding.
