Troubleshooting Flapping Bgp Routes Recursive Routing Failure Cisco From cisco.com
Then we configure the neighbor statement with the IP address of the other BGP router and specify the AS that other router is in. R1 configrouter bgp 65002. The router bgp command where AS number is the BGP AS number used by that router same as EIGRP OSPF configuration. Most of these should be rare as they indicate a problem with the implementation of the BGP protocol.
BGP is classified as a path-vector routing protocol and it makes routing decisions based on paths network policies or rule-sets configured by a network administrator.

In the first line BGP configuration begins with a familiar type of command.
If an error or configuration change occurs that affects the peering session the BGP routing process sends a notification message with the Finite State Machine FSM error code and then transitions to the Idle state. This command goes hand in hand with the listen range command to limit the amount of BGP neighbors that are allowed to connect to the local router. If no peer-group is defined then an error will keep you from committing the configuration. The BGP routing protocol is a service.

TCP port 179 is not open. RFC 7606 defines the error handling procedures for a number of existing attributes. Thanks to BGP Enhanced Attribute Error Handling valid routes exchanged over a session are not impacted because a BGP speaker does not reset a session when malformed BGP Update is received.
The IANA registry for BGP parameters lists a large number of BGP error codes and subcodes for the BGP message types that may appear in a notification message. TCP port 179 is not open. The use of router and route authentication and route integrity greatly mitigates the risk of being attacked by a machine or router that has been configured to share incorrect routing information with another router. Configure the Hold Time for received routes as 180 seconds.
