Overview
Feature Interaction
14. The TMS zl Module forwards the packet to the next-hop router specified
in the route to its destination IP address, tagging the frame for the
forwarding VLAN of the route.
Note that the destination IP address is the NAT destination for traffic to
which destination NAT has been applied. The destination IP address is the
destination in the delivery IP header for traffic that is part of an IPsec or
GRE tunnel.
Packet Flow from the Host Switch Perspective. Figure 1-23 illustrates
the packet flow in a simplified way from the host switch perspective.
Figure 1-23. Traffic Flow in Routing Mode
When Device A wants to send traffic to Device C, the following steps occur:
1. Device A sends the frame to a TMS zl Module MAC address because the
traffic requires routing and the module IP address on VLAN_7 is the
device’s default gateway.
The TMS zl Module might or might not have a unique MAC address for
this IP address. See “TMS VLANs Rules” on page 1-9.
