The show base command output a summary of the instance parameters under a control B-VPLS. The show command for a user B-VPLS indicates the control B-VPLS. The base parameters except for Bridge Priority and Bridge ID must match on neighbor nodes.

The show routes command shows the next hop if for the MAC addresses both unicast and multicast. The path to 00:10:00:01:00:04 (Dut-D) shows the low-path-id algorithm ID. For FID one the neighbor is Dut-B and for FID 100 the neighbor is Dut-C. Because Dut-A is the root of the multicast single tree the multicast forwarding is the same for Dut-A. However, unicast and multicast routes differ on most other nodes. Also the I-SIDs exist on all of the nodes so I-SID base multicast follows the multicast tree exactly. If the I-SID had not existed on Dut-B or Dut-D then for FID 1 there would be no entry. Note only designated nodes (root nodes) show metrics. Non-designated nodes do not show metrics.

The show service spb mfib command shows the programmed multicast ISID MAC addresses in SPB-managed B-VPLS service shows the multicast ISID pbb group mac addresses in SPB-managed B-VPLS. Other types of *,G multicast traffic is sent over the multicast tree and these MACs are not shown. OAM traffic that uses multicast (for example vMEP CCM) takes this path for example.
