Processing<br />
When packets enter through either an Ethernet 802.3 or Token Ring link 802.5, they<br />
are sent to the tunnel for decapsulation if there is a matching entry found in the<br />
tunnel configuration. Once the tunnel pay load is extracted after decapsulation<br />
(based on the pay load type) they are sent to either the IPX router, IP router, or<br />
Bridge. Non-tunneled packets are sent directly to the IP module. Figure 2-5 shows an<br />
example of this operation.<br />
