2010年10月10日 · Multiprotocol BGP (MP-BGP) is an extension to BGP that enables BGP to carry routing information for multiple network layers and address families. MP-BGP can carry the unicast routes used for multicast routing separately from the routes used for unicast IP forwarding.

Enable multiprotocol BGP (MP-BGP) by configuring BGP to carry network layer reachability information (NLRI) for address families other than unicast IPv4, to specify MP-BGP to carry NLRI for the IPv6 address family, or to carry NLRI for VPNs.

2018年9月3日 · BGP is an exterior gateway protocol (EGP) that is used to exchange routing information among routers in different autonomous systems (ASs). BGP routing information includes the complete route to each destination. BGP uses the routing information to maintain a database of network reachability information, which it exchanges with other BGP systems.

The BGP as a Service (BGPaaS) feature allows a guest virtual machine (VM) to place routes in its own virtual routing and forwarding (VRF) instance using BGP.

Define a BGP peer group. BGP peer groups share a common type, peer autonomous system (AS) number, and cluster ID, if present. To configure multiple BGP groups, include multiple group statements.

For the specified BGP address family, allow the local device’s AS number in the received AS paths and specify the number of times the detection of the local device’s AS in the AS_PATH attribute is allowed. If the count exceeds the specified loop count, the system discards this route. For example, if you configure loops 1, the route is discarded if the local device's AS number is …

Enable the accumulated interior gateway protocol (AIGP) BGP attribute on a protocol family. Configuring AIGP on a particular family enables sending and receiving of the AIGP attribute on that family.

The Border Gateway Protocol (BGP) is a standard exterior gateway protocol developed for exchanging routing and reachability information between Autonomous Systems, a collection of IP routing prefixes managed by a single administrative entity. BGP makes routing decisions based on paths and network policies; although historically mainly seen in service provider networks, it …
