route-map
map_name
: Specifies the route-map that contains the criteria to originate default routes.
map_name
must be the name of an existing route-map in the current context.
distribute-list
dist_list
{
in
|
out
}
Filters updates to and from this neighbor based on a route access list.
dist_list
: The name or number of an
existing route-access-list. Default: No filtering is performed.
in
: Indicates that incoming advertised routes should be filtered.
out
: Indicates that outgoing advertised routes should be filtered.
ebgp-multihop
[
max-hop
number
]
Allows EBGP neighbors that are not on directly connected networks.
[ max-hop ]
number
: Specifies the maximum number of hops allowed to reach a neighbor.
number
must
be an integer from 1 through 255. Default hop count: 255
encrypted password
encrypted password
Specifies an encrypted password that is used only inside configuration files. This should be an alphanumeric
string of 1 through 523 characters.
string of 1 through 523 characters.
fall-over bfd [ multihop ]
Enables Bidirectional Fwarding Detection (BFD) multihop support for fallover.
This command adds or modifies a session in BFD for the BGP peer. If there is an existing session in BFD
(same source-address/destination address), BGP or OSPF protocol will be added to the list of clients for the
BFD session. BGP or OSPF will then be notified when there is a change in the BFD session state.
If there is no such BFD session, a new session is added in BFD. For MH-BFD, the session inherits the
parameters including min-tx, min-rx, multiplier and authentication from the multihop-peer configuration in
BFD by matching the destination address. If the parameters (interval) are not configured in BFD, then the
BFD session will be in Admin-down state.
BGP adds a session in BFD only when the BGP peer is Established state. If there is a state transition in bgp
where the peer is no longer in established state, then the bfd session is deleted. It will be added again, once
the peer comes back to Established state.

filter-list
filt_list
{
in
|
out
}
Establishes BGP filters based on an AS path access list.
filt_list
is the name of an existing AS path
access list.
in
: Indicates that incoming advertised routes will be filtered.
out
: Indicates that outgoing advertised routes will be filtered.
max-prefix
max_num
[
threshold
thresh_percent
] [
warning-only
]
The maximum number of prefixes accepted from this peer. When the maximum is exceeded the neighbor
connection is reset.
Default: No maximum prefix limit.
connection is reset.
Default: No maximum prefix limit.
max_num
: Specifies the maximum number of prefixes permitted. This must be an integer from 1 through
4294967295.
[ threshold
thresh_percent ]
: Specifies a percentage value of when the BGP table is full. When this
value is reached, peer warnings are sent to the neighbor and the neighbor connection is reset.
thresh_percent
must be an integer from 1 through 100.
[ warning-only ]
: Specifies that only a warning message is sent when the limit is exceeded. The neighbor
connection is not reset
