Fabric OS 5.3.0 administrator guide 231
domains allows routing around path failures, including path failures through the routers. The multiple paths
to an xlate domain provide additional bandwidth and redundancy.
There are some differences in how the xlate domain is presented in the BB. The BB xlate domains are
topologically connected to FC routers and participate in FC-Protocol in BB. Front domains are not needed
in the BB. As in the case of xlate domain in edge fabric, BB xlate domains provide additional bandwidth
and redundancy by being able to present itself being connected to single or multiple FC routers with each
FC router capable of connecting multiple IFLs to edge fabrics.
Setting up the FC-FC routing service
To set up the FC-FC Routing Service, perform the following tasks:
1. ”Performing verification checks” next
2. “Assigning Backbone Fabric IDs” on page 11-13
3. “Configuring FCIP tunnels (optional)” on page -236
4. “Configuring FC-FC routing to work with Secure Fabric OS (optional)” on page -236
5. “Configuring an interfabric link” on page -238
6. “FC router port cost (optional)” on page -246
7. “EX_Port frame trunking (optional)” on page -249
8. “Configuring LSANs and zoning” on page -243
See ”Configuring Directors” on page 207 for more details about configuration options.
Performing verification checks
Before configuring a fabric to connect to another fabric, you must perform the following verification checks
on the switch or director.
To perform verification checks
1. Log in to the switch or director as admin and enter the version command. Verify that Fabric OS
v5.2.x is installed on the 400 MP Router or B-Series MP Router blade, as shown in the following
example.
2. If configuring the 4/256 SAN Director with a B-Series MP Router blade, enter the slotShow
command to verify that the B-Series MP Router blade is present.
