I've seen some mention of multiple fabricpath topologies, but am unable to find much in the way of example configuration. Is this a supported feature at this time? I've got Nexus 7004s at one site and 7010s at another both running 6.1(3).
We've got fabricpath running as a DCI between a current site and a new DC. Eventually I want to migrate all VLANs from our old 6500 core at the existing location, but I have some VLAN ID overlap with the new DC and I'd like to keep them separate. In classical ethernet trunking I'd use the "switchport trunk allowed vlan" command, but I'm told that there's no equivelent for fabricpath interfaces.
Solved! Go to Solution.
Multi Topology tree are available now and I am working extensively on them in LAB.
As a small template you can use the following reference from Cisco :
|Command or Action||Purpose|
|Step 1||switch# configure terminal||Enters global configuration mode.|
|Step 2||switch(config)# fabricpath topology id|
Creates a new fabricpath topology and enters the FabricPath topology configuration mode.
|Step 3||switch(config-fp-topology)# member vlan range|
Configures the VLANs for the topology. The range of the VLAN ID is from 1 to 4094.
|Step 4||switch(config-fp-topology)# exit|
Exits FabricPath topology configuration mode.
|Step 5||switch(config)# interface port-channel number|
Configures a port-channel interface and enters interface configuration mode. You can configure any of the available interfaces.
|Step 6||switch(config-if)# fabricpath topology-member id|
Adds the interface to the topology.
|Step 7||switch(config-if)# exit|
Exits interface configuration mode.
|Step 8||switch(config)# exit|
Exits global configuration mode.
|Step 9||switch# show fabricpath topology vlan||(Optional)|
Displays information about the VLANs in the Layer 2 topology.
|Step 10||switch# show fabricpath isis topology summary||(Optional)|
Displays information about the IS-IS summary topology.
|Step 11||switch# copy running-config startup-config||(Optional)|
Copies the running configuration to the startup configuration.
This example shows how to create a topology, map VLANs to the topology, and add an interface to the topology.
switch# configure terminal switch(config)# fabricpath topology 1 switch(config-fp-topology)# member vlan 7-19 switch(config-fp-topology)# exit switch(config)# interface port-channel 1 switch(config-if)# fabricpath topology-member 1 switch(config-if)# exit switch(config)# show fabricpath topology vlan switch(config)# show fabricpath isis topology summary
Thanks for the wonderful rating, even though I have not helped you anything much.
I am working more on NZ OS 7.x testing case scenarios these days so that we can implement up-gradations in coming time.
I have made one lab for proof of concept for one customer although there is not much Multi topology configuration available online in Cisco or other places.
I have tried for the 3 topologies..
VLAN 10, 20 , 30
have you experience when you create port channels, that Vlans are leaking.
I am experiencing VLAN are leaking.
Could you please share what you have configured in your production environment.
You may not have helped me personally, but it was a good post and may help someone else. :)
In my fabricpath topology I have:
Both the old Data Center and the redundant Data Center have offices co-located in the same building, thus the desire for the local-only topologies.
This topology has performed as expected with no issues.
I'm not sure what you mean by VLAN leaking.
