72 Using the FCIP Tunneling Service
Configuring an FCIP interswitch link
You must configure both the local and the remote MP Routers to enable an FCIP ISL. This configuration
requires the use of the portCfgFcip command (not the portCfgExPort command).
If the two MP Routers have a direct connection between them (no router in between), the IP addresses for
both routers must be in the same subnet, and the default gateway setting is not required.
If two MP Routers are connected through a router, the IP addresses for both MP Routers must be in different
subnets and the default gateway must be set on both the MP Routers. (Typically, the default gateway is the
router's IP address.)
The basic steps for configuring an FCIP ISL between two MP Routers are:
1. Configure the local MP Router:
a. Issue the portStop command to stop a port.
b. Issue the portType command to configure the port for GigE.
c. Issue the portCfgGige command to configure the IP network parameters and ensure that the port
is set as an FCIP GigE port.
d. Issue the portCfgFcip command to enable the VE_Port.
2. Configure the remote MP Router:
a. Issue the portStop command to stop a port.
b. Issue the portType command to configure the port to be a GigE port.
c. Issue the portCfgGige command to configure the IP network parameters.
d. Issue the portCfgFcip command to enable the VE_Port and configure the VE_Port to initiate the
setup of the FCIP ISL.
NOTE: For all Continuous Access EVA configurations using FCIP, you must set trunking to SID_DID or
none. See the FCIP portcfgfcip command.
NOTE: All ports on an MP Router are optical ports. To connect a VE_Port to a copper network, use an
optical-to-copper converter.
Figure 14 illustrates the topology and port values used in the configuration example in the following two
procedures.
Figure 14 Example for configuration procedures
The configuration example uses the following values:
• Port 1 (IP address 10.2.3.22) on the local MP Router
• Port 4 (IP address 10.2.3.23) on the remote MP Router
• IP network subnet mask 255.255.255.0
