PurposeCommand or Action
Configures TCP maximum segment size. The range is from
68 to 10000.
tcp mss segment-size
Example:
RP/0/RSP0/CPU0:router(config-bgp-nbrgrp)# tcp
mss 500
Step 6
Specifies the IPv4 address family unicast and enters address
family configuration mode.
address-family ipv4 unicast
Example:
RP/0/RSP0/CPU0:router(config-bgp-nbrgrp)#
address-family ipv4 unicast
Step 7
Exits router address family configuration mode.exit
Example:
RP/0/RSP0/CPU0:router(config-bgp-nbrgrp-af)#
exit
Step 8
Exits the neighbor group configuration mode.exit
Example:
RP/0/RSP0/CPU0:router(config-bgp-nbrgrp)# exit
Step 9
Places the router in neighbor configuration mode for BGP
routing and configures the neighbor IP address as a BGP
peer.
neighbor ip-address
Example:
RP/0/RSP0/CPU0:router(config-bgp)# neighbor
10.0.0.2
Step 10
Creates a neighbor and assigns a remote autonomous system
(AS) number to it.
remote-as as-number
Example:
RP/0/RSP0/CPU0:router(config-bgp-nbr)#
remote-as 1
Step 11
•
Range for 2-byte autonomous system numbers (ASNs)
is 1 to 65535.
•
Range for 4-byte autonomous system numbers (ASNs)
in asplain format is 1 to 4294967295.
•
Range for 4-byte autonomous system numbers (ASNs)
is asdot format is 1.0 to 65535.65535.
Specifies that the BGP neighbor inherit configuration from
the specified neighbor group.
use neighbor-group group-name
Example:
RP/0/RSP0/CPU0:router(config-bgp-nbr)# use
neighbor-group n1
