Router bgp configuration mode
Command History
Usage Guidelines The IP prefix to advertise is considered as a best path and advertisement to peers only if a route of equal
or more specificity is present in the routing table.
This command requires the LAN Enterprise Services license.
Examples This example shows how to configure an IP prefix to advertise:
switch# configure terminal
switch(config)# router bgp 64496
switch(config-router)# address-family ipv4 unicast
switch(config-router-af)# network 2.2.2.2 mask 3.3.3.3 route-map test
switch(config-router-af)#
Related Commands
ip-addr IP network address to advertise; use the following format: A.B.C.D.
ip-prefix/length IP prefix and the length of the IP prefix. Use the following format:
A.B.C.D/length.
mask mask-num Configures the mask of the IP prefix to advertise in dotted 4-octet format.
route-map name (Optional) Specifies the name of the route map to modify attributes.
