Greetings HUB Community,
We have a VSP7024 which was configured prior to my involvement. It is behaving as a BCB in an SPBM environment connecting about 15 VSP 4850s in a hub/spoke configuration. System has been working flawlessly.
We recently acquired 8 Windows Servers that we plan on connecting via available 10Gb SFP+ interfaces on the VSP7024. When I took a look at the initial configuration of the 7024, all the ports were configured for ISIS/SPBM connections. I removed the ISIS/SPBM configuration from ports 6 and 8 (where a pair of Windows servers will connect), created vlan 150 and assigned that vlan to the ports. I added an i-sid designation for vlan 150. as well.
On the VSP 4850 I created vlan 150 and assigned that vlan to port 1 (our test laptop). I added the i-sid as well for vlan 150. Seemed simple enough. I can get the servers to ping each other locally. I can get the laptop to ping the 4850 and vice versa. However, I cannot get a successful ping across the SPBM interface. Both switches show vlan 150, both are recognizing the i-sid for vlan 150 (10150) and there is an established ISIS adjacency. Firewalls have been disabled.
I have extracted some relevant config and output info from the 2 switches for your review. Getting ready to involve TAC, but I wanted to start here.

Thanks for the support all. For future searches, a software upgrade from 10.4.0 to 10.4.6 solved the issue.

At first sight it looks fine. Please show us outputs of following commands:
VSP4:
show interface gig vlan 1/1
VSP7:
show vlan interface info 6,8
show vlan interface vids 6,8
Have you tried to check ARP table on VSP4 for the records of the servers connected to VSP7? What software version is running on 7024?
