• Address-family-specific neighbor configuration
• Explicit specification of networks to advertise
The following illustrates CLI options in address-family mode:
switch(config-bgp-router)# address-family ipv4 unicast
switch(config-bgp-ipv4u)# ?
Possible completions:
aggregate-address Configure BGP aggregate entries
always-propagate Allow readvertisement of best BGP routes not in IP
Forwarding table
bgp-redistribute-internal Allow redistribution of iBGP routes into IGPs
client-to-client-reflection Configure client to client route reflection
dampening Enable route-flap dampening
default-information-originate Originate Default Information
default-metric Set metric of redistributed routes
do Run an operational-mode command
exit Exit from current mode
help Provide help information
maximum-paths Forward packets over multiple paths
multipath Enable multipath for ibgp or ebgp neighbors only
neighbor Specify a neighbor router
network Specify a network to announce via BGP
next-hop-enable-default Enable default route for BGP next-hop lookup
next-hop-recursion Perform next-hop recursive lookup for BGP route
no Negate a command or set its defaults
pwd Display current mode path
redistribute Redistribute information from another routing
protocol
rib-route-limit Limit BGP rib count in routing table
static-network Special network that do not depends on IGP and
always treat as best route in BGP
table-map Map external entry attributes into routing table
top Exit to top level and optionally run command
update-time Configure igp route update interval
BGP global mode
Configurations that are not specific to address-family configuration are available in the BGP global
configuration mode:
switch(config-bgp-router)# ?
Possible completions:
address-family Enter Address Family command mode
always-compare-med Allow comparing MED from different neighbors
as-path-ignore Ignore AS_PATH length for best route selection
capability Set capability
cluster-id Configure Route-Reflector Cluster-ID
compare-med-empty-aspath Allow comparing MED from different neighbors even with
empty as-path attribute
compare-routerid Compare router-id for identical BGP paths
default-local-preference Configure default local preference value
distance Define an administrative distance
enforce-first-as Enforce the first AS for EBGP routes
fast-external-fallover Reset session if link to EBGP peer goes down
install-igp-cost Install igp cost to nexthop instead of MED value as
BGP cost
local-as Configure local AS number
log-dampening-debug Log dampening debug messages
maxas-limit Impose limit on number of ASes in AS-PATH attribute
med-missing-as-worst Consider routes missing MED attribute as least
desirable
neighbor Specify a neighbor router
timers Adjust routing timers
Neighbor configuration
For each neighbor a device is going to peer with, there must be a neighbor configuration that specifies
an IP address (which must be the primary IP address of interface connection to get established) and
BGP global mode
