Chapter Unicast Routing Commands
advertise-map (BGP)
advertise-map (BGP)
To configure Border Gateway Protocol (BGP) conditional advertisement, use the advertise-map
command. To remove BGP conditional advertisement, use the no form of this command.
advertise-map adv-map {exist-map exist-rmap | non-exist-map nonexist-rmap}
Syntax Description
Command Default None
Command Modes BGP neighbor address-family command mode
Command History
Usage Guidelines Use the advertise-map command to conditionally advertise selected routes. The routes or prefixes that
BGP conditionally advertises are defined in two route maps, the adv-map and an exist-map or
nonexist-map. The exist-map or nonexist-map specifies the prefix that the BGP tracks. The adv-map
specifies the prefix that BGP advertises to the specified neighbor when the condition is met.
This command requires the LAN Enterprise Services license.
Examples This example shows how to configure BGP conditional advertisement:
switch# configure terminal
switch(config)# router bgp 65536
switch(config-router)# neighbor 192.0.2.2 remote-as 65537
switch(config-router-neighbor)# address-family ipv4 unicast
switch(config-router-neighbor-af)# advertise-map advertise exist-map exist
switch(config-router-neighbor-af)# exit
switch(config-router-neighbor)# exit
switch(config-router)# exit
switch(config)# route-map advertise
switch(config-route-map)# match as-path pathList
switch(config-route-map)# exit
switch(config)# route-map exit
switch(config-route-map)# match ip address prefix-list plist
adv-map Route map with match statements that the route must pass before BGP passes
theroute to the next route map. The adv-map is a case-sensitive, alphanumeric
string up to 63 characters.
exist-map
exist-rmap
Specifies a route map with match statements for a prefix list. A prefix in the BGP
table must match a prefix in the prefix list before BGP will advertise the route.
The exist-rmap is a case-sensitive, alphanumeric string up to 63 characters.
non-exist-map
nonexist-rmap
Specifies a route map with match statements for a prefix list. A prefix in the BGP
table must not match a prefix in the prefix list before BGP will advertise the route.
The nonexist-rmap is a case-sensitive, alphanumeric string up to 63 characters.
Release Modification
5.0(3)A1(1) This command was introduced.
