ibgp: Indicates the Internal Border Gateway Protocol while while configuring maximum-paths and the value should be integer between 1 and 10
Important: If configured under the router-bgp-mode, multipath is enabled only for the prefixes learnt in the default-vrf. There is no support for vpnv4 prefixes even though multipath is turned on for the default-vrf. If configured under the address-family-vrf-mode, multipath is enabled only for prefixes learnt in the vrf.[ no ] neighbor ip_address { activate | advertisement-interval adv_time | capability graceful-restart | default-originate [ route-map map_name ] | distribute-list dist_list { in | out } | ebgp-multihop [ max-hop number ] encrypted password encryp_password fall-over bfd multihop | filter-list filt_list { in | out } | max-prefix max_num [ threshold thresh_percent ] [ warning-only ] next-hop-self | password password | remote-as AS_num | remove-private-AS | restart-time rest_time | route-map map_name { in | out} | send-community { both | extended | standard } | shutdown | srp-activated-soft-clear | timers { connect-interval connect_interval [ keepalive-interval keepalive_interval holdtime-interval holdtime_interval [ min-peer-holdtime-interval min_peer_hold_interval ] ] | keepalive-interval keepalive_interval holdtime-interval holdtime_interval { connect-interval connect_interval | min-peer-holdtime-interval min_peer_hold_interval [ connect-interval connect_interval ] } } | update-source ip_address | weight value }
neighbor ip_address
ip_address is IPV4 address in dotted desimal or IPV6 address saperated by colon.
advertisement-interval adv_time
adv_time must be an integer from 0 through 600.
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.
dist_list: The name or number of an existing route-access-list.
in: Indicates that incoming advertised routes should be filtered.
out: Indicates that outgoing advertised routes should be filtered.
max-hop number: The maximum number of hops allowed to reach a neighbor. number must be an integer from 1 through 255.
encrypted password encryp_password
filt_list: 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_num: Specifies the maximum number of prefixes permitted. This must be an integer from 1 through 4294967295.
threshold thresh_percent: A percentage value which specifies that when the BGP table is the specified percentage full from this peer warnings are sent to the neighbor. thresh_percent must be an integer from 1 through 100.
warning-only: This keyword specifies that only a warning message is sent when the limit is exceeded. The neighbor connection is not reset
ip_address Disables the next hop calculation for this neighbor.
passwordpassword
remote-as AS_num
AS_num: The neighbor’s autonomous system number. must be an integer from 1 through 4294967295.
restart-time rest_time
map_name: Specifies the route-map apply. map_name must be the name of an existing route-map in the current context.

timers { [ connect-interval connect_interval ] | [ keepalive-interval keepalive_interval holdtime-interval holdtime_interval ] }
connect-interval connect_interval: Specifies the connect timer in seconds. conn_time must be an integer from 0 through 65535. The default is 60 seconds.
keepalive-interval keepalive_interval : The frequency, in seconds, at which the current BGP router sends keepalive messages to its neighbor. keep_time must be an integer from 0 through 65535. The default is 30 seconds.
holdtime-interval holdtime_interval: The interval, in seconds, the router waits for a keepalive message before declaring a neighbor dead. hold_time must be an integer from 0 through 65535. The default is 90 seconds.
min-peer-holdtime-interval min_peer_hold_interval : Minimum acceptable hold time from peer for a keepalive message before declaring a neighbor dead. min_peer_hold_interval must be an integer from 0 through 65535. The default is 90 seconds.
update-source ip_address
Use this keyword to bind the specified IP address to the bgp socket that is used to communicate to the peer. ip_address is an IPv4 address in dotted decimal notation.
weight value
value: This must be an integer from 0 through 65535.
Important: A remote AS number must be specified for a neighbor before other parameters can be configured.The following command specifies that the neighbor at the IP address 192.168.100.25 has an AS number of 2000:
Specifies the IP address and netmask bits for the network to announce via BGP. ip_address is a network IP address (in dotted-decimal notation) and mask is the number of subnet bits, representing a subnet mask in shorthand. These must be entered in the IPv4 dotted-decimal notation/subnet bits format .
route-map map_name
route-map map_name
map_name specifies the name of the route-map to use and must be specified as a string of 1 through 79 alphanumeric characters
