# RouteServerBgpOptions


The BGP configuration options for a route server peer.

## Contents


 ** peerAsn **   
The Border Gateway Protocol (BGP) Autonomous System Number (ASN) for the appliance. Valid values are from 1 to 4294967295. We recommend using a private ASN in the 64512–65534 (16-bit ASN) or 4200000000–4294967294 (32-bit ASN) range.  
Type: Long  
Required: No

 ** peerLivenessDetection **   
The liveness detection protocol used for the BGP peer.  
The requested liveness detection protocol for the BGP peer.  
+  `bgp-keepalive`: The standard BGP keep alive mechanism ([RFC4271](https://www.rfc-editor.org/rfc/rfc4271#page-21)) that is stable but may take longer to fail-over in cases of network impact or router failure.
+  `bfd`: An additional Bidirectional Forwarding Detection (BFD) protocol ([RFC5880](https://www.rfc-editor.org/rfc/rfc5880)) that enables fast failover by using more sensitive liveness detection.
Defaults to `bgp-keepalive`.  
Type: String  
Valid Values: `bfd | bgp-keepalive`   
Required: No
