Advanced Setup – Dynamic Routing (BGP)

BEC 4700A / 4700AZ User Manual
❖ Border Gateway Protocol (BGP)
A standardized exterior gateway protocol (an uniquely TCP based 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 the 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: The indication of the rule number. The maximum entry is up to 10, ranging from 0 to 9.
Neighbor IP: Enter the neighbor IP address.
Neighbor AS Number: Enter the neighbor 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, an 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.
Soft-reconfiguration inbound: Enable to save, pre-stored, a new inbound policy to the BGP table
without interrupting the network when applying this new policy.
EBGP (External BGP)-multihop: Enable to build up peer connection/information with external
neighbors.
