EX 4200, 3200 switches participating in Provider RSTP
I have a QinQ network where it basicly forms a triangle 2 parts of the triangle are a Ceragon product, and the 3rd is a juniper EX4200. I am trying to congure RSTP on them. The problem is that the Ceragon and the Juniper will not communicate their BPDU frames to each other. The reason (I beleive) is that the Ceragons are sending their BPDU to 01:80:c2:00:00:08 while the Juniper is sending it to 01:80:c2:00:00:00.
states "In addition to the TPID EtherType value of 0x8100, EX Series switches that run Junos OS that does not support the Enhanced Layer 2 Software (ELS) configuration style also support values of 0x88a8 (Provider Bridging and Shortest Path Bridging) and 0x9100 (Q-inQ)."
So this suggests non-ELS switches such as the 4200 support provider bridging via ethertype as opposed to MAC address.
