Cisco IOS XR Routing Configuration Guide
Step 10
password {clear | encrypted}
password
Example:
RP/0/RP0/CPU0:router(config-bgp-nbrgrp)#
password clear pswd123
(Optional) Configures neighbor group nbr-grp-A to use
MD5 authentication with the password pswd123.
Step 11
password-disable
Example:
RP/0/RP0/CPU0:router(config-bgp-nbrgrp)#
password-disable
(Optional) Overrides any inherited password configuration
from the neighbor group.
Step 12
receive-buffer-size
socket-size
[
bgp-size
]
Example:
RP/0/RP0/CPU0:router(config-bgp-nbrgrp)#
receive-buffer-size 45215 5156
(Optional) Sets the receive buffer sizes for neighbor group
nbr-grp-A to 45215 bytes for the socket buffer and 5156
bytes for the BGP buffer.
Step 13
send-buffer-size
socket-size
[
bgp-size
]
Example:
RP/0/RP0/CPU0:router(config-bgp-nbrgrp)#
send-buffer-size 8741 8741
(Optional) Sets the send buffer sizes for neighbor group
nbr-grp-A to 8741 bytes for the socket buffer and 8741
bytes for the BGP buffer.
Step 14
timers
keepalive hold-time
Example:
RP/0/RP0/CPU0:router(config-bgp-nbrgrp)# timers
60 220
(Optional) Sets the keepalive timer to 60 seconds and the
hold-time timer to 220 seconds for the BGP neighbor group
nbr-grp-A.
Step 15
ttl-security
Example:
RP/0/RP0/CPU0:router(config-bgp-nbrgrp)#
ttl-security
(Optional) Enables TTL security for eBGP neighbor group
nbr-grp-A.
Step 16
update-source
interface-type interface-number
Example:
RP/0/RP0/CPU0:router(config-bgp-nbrgrp)#
update-source Loopback0
(Optional) Configures the router to use the IP address from
the Loopback0 interface when trying to open a session with
neighbor group nbr-grp-A.
Step 17
exit
Example:
RP/0/RP0/CPU0:router(config-bgp-nbrgrp)# exit
Exits the current configuration mode.
Step 18
neighbor
ip-address
Example:
RP/0/RP0/CPU0:router(config-bgp)# neighbor
172.168.40.24
Places the router in neighbor configuration mode for BGP
routing and configures the neighbor IP address
172.168.40.24 as a BGP peer.
