Chapter38 Configuring IP Unicast Routing
Configuring BGP
Step7 neighbor {ip-address | peer-group-name}
default-originate [route-map map-name](Optional) Allow a BGP speaker (the local router) to send the
default route 0.0.0.0 to a neighbor for use as a default route.
Step8 neighbor {ip-address | peer-group-name}
send-community (Optional) Specify that the COMMUNITIES attribute be sent to
the neighbor at this IP address.
Step9 neighbor {ip-address | peer-group-name}
update-source interface (Optional) Allow internal BGP sessions to use any operational
interface for TCP connections.
Step10 neighbor {ip-address | peer-group-name}
ebgp-multihop (Optional) Allow BGP sessions, even when the neighbor is not
on a directly connected segment. The multihop session is not
established if the only route to the multihop peer’s address is the
default route (0.0.0.0).
Step11 neighbor {ip-address | peer-group-name}
local-as number (Optional) Specify an AS number to use as the local AS. The
range is 1 to 65535.
Step12 neighbor {ip-address | peer-group-name}
advertisement-interval seconds (Optional) Set the minimum interval between sending BGP
routing updates.
Step13 neighbor {ip-address | peer-group-name}
maximum-prefix maximum [threshold](Optional) Control how many prefixes can be received from a
neighbor. The range is 1 to 4294967295. The threshold
(optional) is the percentage of maximum at which a warning
message is generated. The default is 75 percent.
Step14 neighbor {ip-address | peer-group-name}
next-hop-self (Optional) Disable next-hop processing on the BGP updates to a
neighbor.
Step15 neighbor {ip-address | peer-group-name}
password string (Optional) Set MD5 authentication on a TCP connection to a
BGP peer. The same password must be configured on both BGP
peers, or the connection between them is not made.
Step16 neighbor {ip-address | peer-group-name}
route-map map-name {in | out}(Optional) Appl y a ro ute m ap to in co ming or out going r oute s.
Step17 neighbor {ip-address | peer-group-name}
send-community (Optional) Specify that the COMMUNITIES attribute be sent to
the neighbor at this IP address.
Step18 neighbor {ip-address | peer-group-name} timers
keepalive holdtime (Optional) Set timers for the neighbor or peer group.
•The keepalive interval is the time within which keepalive
messages are sent to peers. The range is 1 to 4294967295
seconds; the default is 60.
•The holdtime is the interval after which a peer is declared
inactive after not receiving a keepalive message from it. The
range is 1 to 4294967295 seconds; the default is 180.
Step19 neighbor {ip-address | peer-group-name} weight
weight (Optional) Specify a weight for all routes from a neighbor.
Step20 neighbor {ip-address | peer-group-name}
distribute-list {access-list-number | name} {in |
out}
(Optional) Filter BGP routing updates to or from neighbors, as
specified in an access list.
Step21 neighbor {ip-address | peer-group-name}
filter-list access-list-number {in | out | weight
weight}
(Optional) Establish a BGP filter.
Step22 neighbor {ip-address | peer-group-name}
version value (Optional) Specify the BGP version to use when communicating
with a neighbor.
