802.1AQ SUPPORT OVER IETF EVPN |
| 摘要 |
A method is implemented in a provider edge switch (PE) for interworking an 802.1aq control plane with an Ethernet Virtual Private Network (EVPN) Border Gateway Protocol (BGP) control plane. The method includes receiving an Intermediate System-Intermediate System (IS-IS) protocol data unit (PDU) including an IS-IS Type Length Value (TLV) by the PE and determining whether the received IS-IS PDU requires a change in a configuration of designated forwarder (DF). The method further includes determining whether the PE is still the DF for one or more Backbone-Virtual Local Area Network Identifiers (B-VIDs), and removing local DF associated network layer reachability information (NLRI) from a BGP database |

1. A method implemented in a provider edge switch (PE) for interworking an 802.1aq control plane with an Ethernet Virtual Private Network (EVPN) Border Gateway Protocol (BGP) control plane, the method comprising the steps of:
receiving an Intermediate System-Intermediate System (IS-IS) protocol data unit (PDU) including an IS-IS Type Length Value (TLV) by the PE; determining whether the received IS-IS PDU requires a change in a configuration of designated forwarder (DF); determining whether the PE is still the DF for one or more Backbone-Virtual Local Area Network Identifiers (B-VIDs); and removing local DF associated network layer reachability information (NLRI) from a BGP database and remote NLRI from an IS-IS database, in response to the PE no longer being the DF. |
