Multiprotocol BGP (MP-BGP) Configuration. The normal version of BGP (Border Gateway Protocol) only supported IPv4 unicast prefixes. MP-BGP is also used for MPLS VPN where we use MP-BGP to exchange the VPN labels. For each different "address" type, MP-BGP uses a different address family. BCP 214 / RFC 8327 BGP Session Culling Compliance. Bogon ASN Filter Policy. NTT GIN BGP-4 NEXT_HOP Policy. The NTT GIN network has stricter requirements for IP addresses in the BGP NEXT_HOP attribute than RFC 4271 mandates. RFC 4271 allows any IP address that is part of a Network Working Group T.

BGP is the routing protocol that runs the Internet. It is an increasingly popular protocol for use in the data center as it lends itself well to the rich interconnections in a Clos topology. Routing Protocol for exchanging information between networks. BGP Operations and Security. RFC4271. !11. Sources of information. - Information about the local BGP speaker. - Version and Hold time - AS number and Router-ID. - BGP Capabilities Advertisement - RFC 2842. RFC 8212 updates the core BGP specification (RFC 4271) by defining the default behavior of a BGP speaker when there is no Import or Export Policy associated with an External BGP session.

RFC 2547bis VPNs are also known as BGP/MPLS VPNs because BGP is used to distribute VPN routing information across the provider's OSPF RFC Compatibility. RFC 2328 and RFC 1583 specify different methods for calculating summary route metrics. switch#show ip route Codes: C - connected, S - static, K - kernel, O - OSPF, B - BGP.
