13.6.8.1 Provisioning IP-over-CLNS Tunnels
IP-over-CLNS tunnels must be carefully planned to prevent nodes from losing visibility or connectivity.
Before you begin a tunnel, verify that the tunnel type, ei ther Cisco IP or GRE, is supported by the
equipment at the other end. Always verify IP and NSAP addresses. Provisioning of IP-over-CLNS
tunnels in CTC is performed on the node view Provisioning > OSI > IP over CLNS Tunnels tab. For
procedures, refer to the “Turn Up a Node” chapter in the Cisco ONS 15454 Procedure Guide.
Provisioning IP-over-CLNS tunnels on Cisco routers requires the following prerequisite tasks, as well
as other OSI provisioning:
(Required) Enable IS-IS
(Optional) Enable routing for an area on an interface
(Optional) Assign multiple area addresses
(Optional) Configure IS-IS interface parameters
(Optional) Configure miscellaneous IS-IS parameters
The Cisco IOS commands used to create IP-over-CLNS tunnels (CTunnels) are shown in Table 13-14.
