Proxy of Routing Protocols to Redundant Controllers |
| 摘要 |
In an embodiment, a method exchanges routing data within a network including control and forwarding on separate devices. In the method, a first reachability information session is established between a forwarding device and a first control device and a second reachability information session is established between the forwarding device and a second control device. Also, a third reachability information session is established between the forwarding device and an external routing device. Finally, advertisements are exchanged between the first and second reachability information sessions and the third reachability information session such that the first and second control device appear to the external routing device to be a single device. System and computer program product embodiments are also disclosed. |

1. A method for exchanging routing data with a network including control and forwarding on separate devices, comprising:
(a) establishing a first reachability information session between a forwarding device and a first control device and a second reachability information session between the forwarding device and a second control device such that the first and second reachability information sessions enable the respective first and second control devices to send advertisements indicating what addresses are reachable through the network; (b) establishing a third reachability information session between the forwarding device and an external routing device such that third reachability information session enables the forwarding device to exchange the advertisements with the external routing device indicating what addresses are reachable through the respective forwarding and external routing devices; and (c) exchanging, at the forwarding device, the advertisements between the first and second reachability information sessions and the third reachability information session such that the first and second control device appear to the external routing device to be a single device. |
