Configuring BGP Neighbor Parameters

BGP Neighbor Configuration describes the configuring of BGP neighbor parameters.

BGP Neighbor Configuration

Task	Command
In BGP configuration mode, configure the remote AS for the peer.	neighbor ip-address remote-as as-num
In BGP configuration mode, optionally configure EBGP peer routes to not contain this neighbor‘s AS.	neighbor ip-address ignore-leading-as
In BGP configuration mode, optionally remove private autonomous system (AS) numbers from outbound updates to an external peer.	neighbor {ip-address | groupID} remove-private-as
In BGP configuration mode, optionally modify the minimum interval between the sending of EBGP routing updates.	neighbor ip-address advertisement-interval interval
In BGP configuration mode, optionally configure the conditional advertisement of routes for this neighbor.	neighbor {ip-address | groupID} advertise-map adv-map non-exist-map non-exit-map
In BGP configuration mode, optionally enable the inclusion of confederation information in the AS paths sent to this router‘s peers.	neighbor {ip-address | groupID} aggregate-confed
In BGP configuration mode, optionally modify the interval between successive update messages for route prefixes that originate in the local AS.	neighbor ip-address as-origination-interval interval
In BGP configuration mode, optionally enable checking to see if the next hop is the peer‘s address and do not send routes if it is.	neighbor ip-address check-next-hop
In BGP configuration mode, optionally clear all BGP counters for this peer.	neighbor ip-address clear-counters
In BGP configuration mode, optionally configure the specified neighbor as a member of the router's confederation.	neighbor ip-address confed-member
In BGP configuration mode, optionally modify the amount of time between attempts to reestablish a connection to configured peers that are no longer available.	neighbor ip-address connect-retry-interval interval
In BGP configuration mode, optionally force the advertisement of the default route regardless of whether the default route is present in the local routing table.	neighbor ip-address default-originate [route-map name]
In BGP configuration mode, explicitly enable a peer that has been administratively disabled. A configured peer is enabled by default.	neighbor ip-address enable
In BGP configuration mode, optionally modify the interval between returning to the idle state and reinitiating a TCP connection for this neighbor.	neighbor ip-address idle-hold-interval interval
In BGP configuration mode, optionally configure EBGP peer routes to not contain this neighbor‘s AS.	neighbor ip-address ignore-leading-as
In BGP configuration mode, optionally modify the maximum number of Outbound Route Filtering (ORF) entries that will be accepted from this neighbor.	neighbor ip-address maximum-orf num
In BGP configuration mode, optionally modify the peak number of prefixes that BGP will accept for installation into the Routing Information Base (RIB).	neighbor ip-address maximum-prefix num [warning-only]
In BGP configuration mode, optionally configure BGP to always set the BGP next hop to the EBGP peer's address, overriding third-party next hops.	neighbor {ip-address | groupID} next-hop-peer
In BGP configuration mode, optionally set this neighbor‘s next hop as the router's own address on advertisement.	neighbor {ip-address | groupID} next-hop-self
In BGP configuration mode, optionally modify the interval between the establishment of a TCP connection and the sending of an OPEN message to open a BGP session.	neighbor ip-address open-delay seconds
In BGP configuration mode, optionally prevent the router from ever trying to open a BGP connection with the specified peer.	neighbor ip-address passive
In BGP configuration mode, optionally create a BGP peer group and add a peer group neighbor.	neighbor groupID peer-group neighbor ip-address peer-group pgname
In BGP configuration mode, optionally configure the peer type of the specified peer or group.	neighbor {ip-prefix/length | groupID} peer-type {ibgp | ebgp | ebgp-confed}
In BGP configuration mode, optionally configure whether updates for prefixes containing the NOPEER community will be accepted by or sent to this neighbor.	neighbor {ip-address | groupID} peering-type {bilateral | unspecified}
In BGP configuration mode, optionally specify a BGP route-map to be used for controlling the import or export of routes to and from the specified peer or group.	neighbor {ip-address | groupID} route-map rm-name {in | out}
In BGP configuration mode, optionally specify that the router will act as a route reflector for this neighbor.	neighbor ip-address route-reflector-client
In BGP configuration mode, optionally modify the interval between the advertisement and subsequent withdrawal of a route.	neighbor ip-address route-withdraw-interval interval
In BGP configuration mode, optionally enable soft-reconfiguration for a peer or peer group.	neighbor {ip-address | groupID} soft-reconfiguration
In BGP configuration mode, optionally modify holdtime and keepalive time values within a BGP peer.	neighbor ip-address timers keepalive-value holdtime-value
In BGP configuration mode, optionally modify the time to live (TTL) value.	neighbor ip-address ttl ttl-num
In BGP configuration mode, optionally specify the source IP address to be used in all TCP and BGP messages sent to the peer.	neighbor ip-address update-source source-addr
