Traffic flow from the PSD to the RSD over a shared interface is as follows:
A packet destined for the shared PIC at the RSD is received on an interface at the PSD
1.
and sent to the Packet Forwarding Engine on the PSD's tunnel PIC. (The tunnel PIC
is configured to peer with the shared PIC at the RSD.)
The packet is sent out of the tunnel interface.
2.
The tunnel PIC loops the packet back to the input side of its Packet Forwarding Engine
3.
and the packet is sent over the switch fabric to the Packet Forwarding Engine on the
shared PIC at the RSD.
The packet is then sent out the shared interface.
4.
Traffic flow from the RSD to the PSD is as follows:
The Packet Forwarding Engine on the shared PIC at the RSD determines on which
1.
logical interface the packet arrived.
Based on the RSD configuration, the PSD that is associated with this logical interface
2.
is known and the packet is sent over the switch fabric to the tunnel PIC at that PSD.
The packet is sent out the tunnel interface.
3.
The tunnel PIC loops the packet back to the input side of its Packet Forwarding Engine
4.
and the packet is then handled as if it had arrived on a directly-connected PIC.
Table 2 on page 7 lists the PICs that support shared interfaces:
