BGP Terminology
- AS - Autonomous System
- ASN - Autonomous System Number
- NLRI - Network Layer Reachability Information is what is being exchanged between BGP peers and represents how to reach the prefixes.
- IGP - Interior Gateway Protocol
- EGP - Exterior Gateway protocol
- RR - Route reflector is the router in the BGP network that reflects advertisements to all the neighbors, avoiding the requirement for full BGP mesh.
- Route server - is the BGP router that does not participate in traffic forwarding. Routes are typically not even installed in the FIB.
- loopback address - a /32 address configured on a dummy bridge interface, that can act as a loopback.

| Property | Description | |
|---|---|---|
| name (string; Default: ) | Name of the BGP connection | |
| connect (yes | no; Default: yes) | Whether to allow the router to initiate the connection. | |
| listen (yes | no; Default: yes) | Whether to listen for incoming connections. | |
| local - a group of parameters associated with the local side of the connection | ||
| .address (IPv4/6; Default: ::) | Local connection address. | |
| .port(integer [0..65535]; Default:179 ) | Local connection port. | |
| .role(ebgp | ebgp-customer | ebgp-peer | ebgp-provider | ebgp-rs | ebgp-rs-client | ibgp | ibgp-rr | ibgp-rr-client; Default: ) | BGP role, in most common scenarios it should be set to iBGP or eBGP. More information on BGP roles can be found in the corresponding RFC draft https://datatracker.ietf.org/doc/draft-ietf-idr-bgp-open-policy/?include_text=1) | |
| .ttl (integer [1..255]; Default:) | Time To Live (hop limit) that will be recorded in sent TCP packets. | |
| remote - a group of parameters associated with the remote side of the connection | ||
| .address (IPv4/6; Default: ::) | Remote address used to connect and/or listen to. | |
| .port(integer [0..65535]; Default:179 ) | Local connection port. | |
| .as(integer []; Default: ) | Remote AS number. If not specified BGP will determine remote AS automatically from the OPEN message. | |
| .allowallowed-as() | List of remote AS numbers that are allowed to connect. Useful for dynamic peer configuration. | |
| .ttl (integer [1..255]; Default:) | Acceptable minimum Time To Live, the hop limit for this TCP connection. For example, if 'ttl=255' then only single-hop neighbors will be able to establish the connection. This property only affects EBGP peers. | |
| tcp-md5-key (string; Default: ) | The key used to authenticate the connection with TCP MD5 signature as described in RFC 2385. If not specified, authentication is not used. | |
| templates (name[,name]; Default: default) | List of the template names, to inherit parameters from. Useful for dynamic BGP peers. | |
