No Agreement Check Configuration Example; Configuring Tc Snooping - HP 6125XLG Configuration Manual

No Agreement Check configuration example

Network requirements
As shown in
Device A connects to a third-party device that has a different spanning tree implementation. Both
•
devices are in the same region.
The third-party device (Device B) is the regional root bridge, and Device A is the downstream
•
device.

Configuring TC Snooping

As shown in
• Device A and Device B form an IRF fabric.
The spanning tree feature is disabled on Device A and Device B and enabled on all devices in user
•
network 1 and user network 2.
User network 1 and user network 2 are connected to the IRF fabric through double links.
•
• The IRF fabric transparently transmits BPDUs for both user networks and is not involved in the
calculation of spanning trees.
When the network topology changes, it takes time for the IRF fabric to update its MAC address table and
ARP table. During this period, traffic in the network might be interrupted.
