DLP-G296 Edit an IP-Over-CLNS Tunnel
Caution
Changing the IP or NSAP addresses or an IP-over-CLNS tunnel can cause loss of NE visibility or NE
isolation. Do not change network addresses until you verify the changes with your network
administrator.
Step 1
Click the
Provisioning > OSI > Tunnels
tabs.
Step 2
Click
Edit
.
Step 3
In the Edit IP Over OSI Tunnel dialog box, complete the following fields:
•
Tunnel Type—Edit the tunnel type:
–
Cisco
—Creates the proprietary Cisco IP tunnel. Cisco IP tunnels add the CLNS header to the
IP packets.
–
GRE
—Creates a generic routing encapsulation (GRE) tunnel. GRE tunnels add the CLNS
header and a GRE header to the IP packets.
The Cisco proprietary tunnel is slightly more efficient than the GRE tunnel because it does not add
the GRE header to each IP packet. The two tunnel types are not compatible. Most Cisco routers
support the Cisco IP tunnel, while only a few support both GRE and Cisco IP tunnels. You generally
should create Cisco IP tunnels if you are tunneling between two Cisco routers or between a Cisco
router and an ONS node.
Caution
Always verify that the IP-over-CLNS tunnel type you choose is supported by the equipment at the other
end of the tunnel.
•
IP Address—Enter the IP address of the IP-over-CLNS tunnel destination.
•
IP Mask—Enter the IP address subnet mask of the IP-over-CLNS destination.
•
OSPF Metric—Enter the Open Shortest Path First (OSPF) metric for sending packets across the
IP-over-CLNS tunnel. The OSPF metric, or cost, is used by OSPF routers to calculate the shortest
path. The default is 110. Normally, it is not changed unless you are creating multiple tunnel routes
and want to prioritize routing by assigning different metrics.
•
NSAP Address—Enter the destination NE or OSI router NSAP address.
Step 4
Click
OK
.
Step 5
Return to your originating procedure (NTP).
Purpose
This task allows you to edit the parameters of an IP-over-CLNS tunnel.
