Peers

Home menu level: /routing bgp peer
Description
You need to specify the BGP peer with whom you want to exchange the routing information. The
BGP exchanges routing information only if it can establish a TCP connection to its peer. You can
add as many peers as required.
Property Description
hold-time ( time ) - specifies the BGP Hold Time value to use when negotiating with peers.
According to BGP specifications, if router does not receive successive KEEPALIVE and/or
UPDATE and/or NOTIFICATION messages within the period specified in the Hold Time field of
the OPEN message, then the BGP connection to the peer will be closed
in-filter ( name ; default: "" ) - name of the routing filter that is applied to incoming routing update
messages
keepalive-time ( time ) - specifies the time interval between successive KEEPALIVE messages.
BGP process will negotiate the keepalive time with the neighbour upon connection establishment
multihop ( yes | no ; default: no ) - if enabled, allows BGP sessions, even when the neighbour is
not on a directly connected segment. The multihop session is not established if the only route to the
multi-hop peer's address is the default route (0.0.0.0/0)
out-filter ( name ; default: "" ) - name of the routing filter that is applied to outgoing routing
