BGP Configuration
The Border Gateway Protocol (BGP) is used between Autonomous Systems (ASs) to transmit routing information. BGP applies to large and complex networks.

- Configuring Basic BGP Functions
Before building a BGP network, you need to configure basic BGP functions. - Configuring BGP Security
Configuring connection authentication and BGP GTSMfor BGP peers can improve BGP network security. - Simplifying IBGP Network Connections
Configuring a route reflector and a confederation on an IBGP network can simplify IBGP network connections. - Configuring BGP Route Selection and Load Balancing
BGP has many route attributes. These attributes can be configured to change the route selection result. - Controlling the Receiving and Advertisement of BGP Routes
Controlling the receiving and advertisement of BGP routes can reduce the routing table size and improve network security. - Adjusting the BGP Network Convergence Speed
You can configure BGP timers, disable rapid EBGP connection reset, and configure BGP route dampening to speed up BGP network convergence and improve BGP security. - Configuring BGP Reliability
You can configure BGP Tracking, association between BGP and BFD, and BGP GR to speed up BGP network convergence and improve BGP reliability. - Configuring BGP Route Summarization
On IPv4 networks, BGP supports automatic route summarization and manual route summarization. Manual route summarization takes precedence over automatic route summarization. On IPv6 networks, BGP supports only manual route summarization. - Configuring On-demand Route Advertisement
If a BGP device only wants to received required routes but its peer cannot maintain different export policies for connected devices, you can configure prefix-based BGP outbound route filtering (ORF) to meet this requirement. - Configuring BGP to Advertise Default Routes to Peers
If a BGP device needs to send multiple routes to its peer, the BGP device can be configured to send only a default route with the local address as the next-hop address to its peer, regardless of whether there are default routes in the local routing table. This function reduces the number of network routes and saves memory and network resources. - Configuring Path MTU Auto Discovery
BGP path maximum transmission unit (MTU) auto discovery can discover the minimum MTU (path MTU) on the network path from the source to the destination so that TCP can transmit BGP messages based on the path MTU. - Configuring MP-BGP
Multiprotocol BGP (MP-BGP) enables BGP to support IPv4 unicast networks, IPv4 multicast networks, and IPv6 unicast networks. - Configuring the Dynamic BGP Peer Function
