Table 6. Additional BGP Neighbor Configuration Options
(config-bgp-neighbor)#a
dvertisement-interval
<value>
Specifies the minimum interval between sending
updates to the neighbor. The default advertisement
interval is 30 seconds for external neighbors and 5
seconds for internal neighbors. Range is 0 to 600
seconds.
(config-bgp-neighbor)#d
escription <text> Identifies the specified interface connected to the BGP
neighbor using up to 80 alphanumeric characters.
(config-bgp-neighbor)#d
istribute-list <ipv4 acl
name> [in | out]
Assigns an inbound or outbound IPv4 ACL to this BGP
neighbor for filtering.
(config-bgp-neighbor)#e
bgp-multihop <value> Configures the maximum hop count of BGP messages
to a neighbor. The default TTL for BGP messages is 1.
Range is 1 to 254 hops.
(config-bgp-neighbor)#h
old-timer <value> Specifies a default hold time for this BGP neighbor.
This is the time interval (in seconds) within which a
keepalive must be received from the peer before it is
declared a dead peer. Range is 0 to 65535 seconds.
(config-bgp-neighbor)#local-as <value> Specifies an AS number that is different from the one
spec
ified in the router bgp command. The AS
number is used when communicating with this BGP
neighbor.
(config-bgp-neighbor)#p
assword <password> Enables MD5 password authentication to a BGP peer
and specifies the password string to be used for
authentication.
(config-bgp-neighbor)#n
ext-hop-self Forces the next-hop attribute to be changed to this
unit’s IPv4 address for each network it advertises to
the iBGP neighbor.
(config-bgp-neighbor)#no
default-originate Prevents the unit from sending the default route to a
BGP neighbor. This is a default setting and cannot be
modified. A default route can be transmitted to a BGP
neighbor by manually entering a default route in BGP
Configuration mode with the network 0.0.0.0 mask
0.0.0.0 command.
(config-bgp-neighbor)#prefi
x-list <name> [in |
out]
Assigns a prefix list to a BGP neighbor and specifies
whether the list will be used to filter inbound or
outbound routes.
(config-bgp-neighbor)#r
oute-map <name> [in |
out]
Applies a previously configured route map entry to a
BGP neighbor and specifies whether this route map
will filter/modify inbound or outbound BGP route
updates.
(config-bgp-neighbor)#so
ft-reconfiguration
inbound
Enables the AOS device to store BGP updates for the
specified neighbor.
(config-bgp-neighbor)#up
date-source
<interface>
Specifies which interface’s IPv4 address will be used
as the source IPv4 address for the BGP TCP
connection.
