Abstract

BGP Route Recorder (BRR) captures and dumps Border Gateway Protocol (BGP) messages received from BGP peers. Passive links are established between the BRR and BGP peers. All incoming and outgoing BGP messages are recorded and timestamped. Rather than tear down BGP peering sessions when errors are encountered, error conditions are recorded, and the BRR may be configured to maintain links across selected BGP errors.

Claims (27)

1. A method of recording Border Gateway Protocol (BGP) messages from BGP peers, the method comprising:

establishing a passive link with at least one BGP peer to receive BGP messages from the at least one BGP peer;

time-stamping and recording the received BGP messages upon arrival; and

maintaining the link with the at least one BGP peer across a selected BGP error, wherein maintaining the link comprises recording, but not sending, a notification message in response to the selected BGP error.

2. The method of claim 1 , wherein maintaining links with the at least one BGP peer across selected BGP errors is configurable with respect to the selected BGP errors.

3. The method of claim 1 , further comprising:

time-stamping and recording outgoing BGP messages.

4. The method of claim 1 , wherein the selected BGP errors comprise message header errors.

5. The method of claim 1 , wherein the selected BGP errors comprise update errors.

6. The method of claim 1 , wherein the selected BGP errors comprise hold timer expired errors.

7. The method of claim 1 , wherein the selected BGP errors comprise finite machine errors.

8. A Border Gateway Protocol (BGP) Route Recorder (BRR) for recording BGP messages from BGP peers, comprising:

means for establishing passive links with the BGP peers, including awaiting the BGP peers to open BGP sessions;

means for receiving BGP messages from the BGP peers;

means for time-stamping and recording all BGP messages from the BGP peers upon arrival; and

means for maintaining the links with the BGP peers across selected BGP errors, wherein maintaining the links comprises recording, but not sending notification messages in response to the selected BGP errors.

9. The BRR of claim 8 , wherein the BRR does not make routing decisions with respect to the received BGP messages from the BGP peer.

10. The BRR of claim 8 , wherein maintaining links with the BGP peer across selected BGP errors is configurable with respect to the selected BGP errors, to prevent continuous recurrence of the selected BGP errors.

11. A non-transitory computer readable medium that includes executable instructions for processing Border Gateway Protocol (BGP) message traffic in a BGP Route Recorder (BRR), said computer readable medium comprising:

code for listening in a passive mode for BGP peers and awaiting the BPG peers to open BGP sessions to establish links between the BRR and BGP peers;

code for receiving BGP messages from the BGP peers;

code for time-stamping and recording all BFP messages from the BGP peers upon message arrival; and

code for maintaining the links with the BGP peers across selected BGP errors, wherein maintaining the links comprises recording, but not sending, notification messages in response to the selected BGP errors.

12. The computer readable medium of claim 11 , wherein the selected BGP errors comprise message header errors.

13. The computer readable medium of claim 11 , wherein the selected BGP errors comprise update errors.

14. The computer readable medium of claim 11 , wherein the selected BGP errors comprise hold timer expired errors.

15. The computer readable medium of claim 11 , wherein the selected BGP errors comprise finite machine errors.
