Hello All, I have a query regarding the behavior of a PE that is a member of an ES and has been configured to be in All-Active mode.
According to section 7.5 the multihomed site redundancy mode is set to RED = 00: A value of 00 means that the multihomed site is operating in All-Active redundancy mode. What defines “operating”? Is this according to local configuration only? In section 7.11 the ‘P’ bit of the L2-ATTR Extended Community MUST be set to 1 for multihoming All-Active scenarios by all active PE(s). What is an “active PE”? Is this according to local configuration only? In section 14.1.1 it states that: For a given ES, if a remote PE has imported the set of Ethernet A-D per ES routes from at least one PE, where the "Single-Active" flag in the ESI Label extended community is set, then that remote PE MUST deduce that the ES is operating in Single-Active redundancy mode. My understanding is that the meaning of “remote PE” is a PE that is not a member of the ES. This statement indicates that the “remote PE” deduces that the ES is operating in Single-Active redundancy mode from the set of Ethernet A-D per ES routes it has received. What should be the behavior of the “local PE” that is a member of the ES ? I could not find this defined in the document. Does the “local PE” assume that the configuration of all attached PEs to the ES is consistent and therefore it sends RED = 00 and sets the ‘P’ bit in the L2-ATTR ? Or does the “local PE” change what it advertises according to what it receives from the other “local PEs” attached to the same ES? Thank you kindly.
