Chapter 12 Cisco Transport Controller Operation
12.6 Using the CTC Launcher Application to Manage Multiple ONS Nodes
The TL1 tunnel transports the TCP traffic to and from ONS ENEs through the OSI-based GNE. TL1
tunnels are similar to the existing static IP-over-CLNS tunnels, GRE, and Cisco IP, that can be created
at ONS NEs using CTC. (Refer to the Cisco ONS product documentation for information about static
IP-over-CLNS tunnels.) However, unlike the static IP-over-CLNS tunnels, TL1 tunnels require no
provisioning at the ONS ENE, the third-party GNE, or DCN routers. All provisioning occurs at the CTC
computer when the CTC Launcher is started.
Figure 12-9 shows examples of two static IP-over-CLNS tunnels. A static Cisco IP tunnel is created from
ENE 1 through other vendor GNE 1 to a DCN router, and a static GRE tunnel is created from ONS ENE 2
to the other vender, GNE 2. For both static tunnels, provisioning is required on the ONS ENEs. In
addition, a Cisco IP tunnel must be provisioned on the DCN router and a GRE tunnel provisioned on
GNE 2.
Figure 12-9 Static IP-Over-CLNS Tunnels
Figure 12-10 shows the same network using TL1 tunnels. Tunnel provisioning occurs at the CTC
computer when the tunnel is created with the CTC Launcher. No provisioning is needed at ONS NEs,
GNEs, or routers.
