BGP
Border Gateway Protocol (BGP) is a standardized exterior gateway protocol (an uniquely TCP
basded inter-Autonomous System routing protocol) designed to allow setting up an inter-domain
dynamic routing system that automatically updates routing tables of devices running BGP in case of
network topology changes.
BGP: Enable to activate BGP routing.
AS Number: Designate the AS number of local router. The AS number is used to identify the IBGP or
EBGP your neighbor is running.The same AS number means the IBGP, and the different means
EBGP.
Rule Index: A totoal 10 BGP rules are allowed, ranging from 0 to 9.
Neighbor IP: Set your neighbor IP.
Neighbor AS Number: Set your neghbor AS number.
Allowas-in: Enable to allow inter-communication between devices in the same AS. If the local and
neighbor AS number are the same, thus, a inter-AS communication, please enable the allowas-in.
Otherwise, the router only support EBGP routing between different domains.
Next-Hop-Self: Enable to use the router’s own loopback address as the next-hop address.
Self-reconfiguration inbound: Enable to tells the router (BGP course) to save all recived updates of
the routing information from all neighbors. When the BGP connections are reset (Clear IP BCP), these
updates are used to generate the new inbound updates.
EBGP-Multihop: Eanble to allows a BGP speaker to establish a peering session with a router that is
not directly connected.
