Hello All,
In section 17.3 of the draft-ietf-bess-rfc7432bis PE-to-CE Network Failures the first paragraph states that: “If the connectivity between the multihomed CE and one of the PEs to which it is attached fails, the PE MUST withdraw the set of Ethernet A-D per ES routes that had been previously advertised for that ES.” … “When the MAC entry on the PE ages out, the PE MUST withdraw the MAC address from BGP.” The last paragraph of that section 17.3 states that: When a PE receives a withdrawal of a particular Ethernet A-D route from an advertising PE, it SHOULD consider all the MAC/IP Advertisement routes that are learned from the same ESI as in the Ethernet A-D route from the advertising PE as having been withdrawn. This optimizes the network convergence times in the event of PE-to-CE failures. Clarification Please could you explain why the PE that has detected the network failure to its CE is retaining the MAC addresses until age-out time, and only then withdrawing the MAC/IP Advertisement routes; while all the remote PEs that receive the withdrawal of the Ethernet A-D route should be considering all the MAC/IP Advertisement routes received from that PE and learned from that ESI as having been withdrawn, without waiting for the withdrawal of the MAC/IP Advertisement routes. This seems to be inconsistent behavior. Thank you kindly.
