Configuring BGP 
Hardware compatibility 
The HP 5500 SI Switch Series does not support BGP. 
BGP overview 
The Border Gateway Protocol (BGP) is a dynamic inter-AS Exterior Gateway Protocol. The three early 
BGP versions are BGP-1 (RFC 1105), BGP-2 (RFC 1163) and BGP-3 (RFC 1267). The current version is 
BGP-4 (RFC 4271), and is the Internet exterior gateway protocol. The term router in this chapter refers 
to both routers and Layer 3 switches, and BGP refers to BGP-4 in this chapter. 
BGP has the...

•   Route -refresh 
They have the same header. 
Figure 71  BGP message header 
 
 
•  Marker —The 16-byte field is used to delimit BG P messages. The Marker must be all ones. 
•   Length —The two-byte unsigned integer indicates the total length of the message. 
•   Ty p e —This one-byte unsigned integer indicates the type code of the message. The following type 
codes are defined: 1–Open, 2-Update, 3-Notification, 4–Keepalive, and 5–Route-refresh. The 
former four listed codes are...

 189 
•  Optional parameters —Used for multiprotocol extensions and other functions. 
Update 
The update messages are used to exchange routing information between peers. It can advertise feasible 
routes or remove multiple unfeasible routes.  
Figure 73 BGP update message format 
 
 
Each update message can advertise a group of feasible  routes with identical attributes, and the routes 
are contained in the network layer reachability information (NLRI) field. The path attributes field carries 
the...

 190 
Keepalive 
Keepalive messages are sent between peers to maintain connectivity. Its format contains only the 
message header. 
Route-refresh 
A route-refresh message is sent to a peer to reques t the specified address family routing information.  
Figure 75  BGP route-refresh message format 
 
 
•  AFI—Address family identifier. 
•   Res—Reserved; set to 0. 
•   SAFI —Subsequent address family identifier.

Usage of BGP path attributes 
•  ORIGIN 
ORIGIN is a well-known mandatory attribute that  defines the origin of routing information (how a 
route became a BGP route). This attribute has the following types: 
{  IGP —Has the highest priority. Routes added to the BGP routing table using the  network 
command have the IGP attribute. 
{  EGP —Has the second highest priority. Routes obtained via EGP have the EGP attribute. 
{ INCOMPLETE —Has the...
