Hi,
Trying to find how to connect an EXOS switch to an existing Fabric core switch which has VOSS. Not clear what configuration to apply to EXOS to create SPBM 1 and enable ISIS on an interface to bring up an adjacency using standard B-VLANs 4051-4052. And then how to extend VLAN using L2 VSNs from EXOS side.
I can create an ISIS area and bring up a neighbor relationship between two EXOS switches but not sure how to integrate with a VOSS Fabric node.
Any help appreciated.
Thanks,
Rob

VOSS does not support IS-IS on UNI ports, only as Fabric Network to Network (NNI) protocol to exchange topology, routes and services. So to connect an EXOS to exchange IP routing tables use OSPF, BGP or RIP to redistribute IP routes into VOSS IS-IS.

Thanks Chris, good article which is for Fabric Attach which they don't use.
I can bring up an adjacency between EXOS in a lab with the following.
EXOS-5
create isis area spbm1
configure isis area spbm1 is-type level 2
configure isis area spbm1 add area-address 49.0000
configure vlan 1 ipaddress 10.10.10.10 255.255.255.0
enable ipforwarding Default
configure isis add vlan Default area spbm1
configure isis area spbm1 system-id 00bb.0005.0005
enable isis area spbm1
EXOS-6
create isis area spbm1
configure isis area spbm1 is-type level 2
configure isis area spbm1 add area-address 49.0000
configure vlan 1 ipaddress 10.10.10.20 255.255.255.0
enable ipforwarding Default
configure isis add vlan Default area spbm1
configure isis area spbm1 system-id 00bb.0006.0006
enable isis area spbm1
But their Fabric uses B-VIDS and L2-VSNs so how does this extend to EXOS switches. Or is FA the only option?
Thanks,
Rob

I read the article and it works pretty well to be fair and maybe the way to connect EXOS is just FA them.
