To view the BGP configuration, use the
show config
command in CONFIGURATION ROUTER BGP
mode. To view a route map configuration, use the
show route-map
command in EXEC Privilege mode.
To view which BGP routes meet an IP community or IP extended community list’s criteria, use the
show
ip bgp {community-list | extcommunity-list}
command in EXEC Privilege mode.
Manipulating the COMMUNITY Attribute
In addition to permitting or denying routes based on the values of the COMMUNITY attributes, you can
manipulate the COMMUNITY attribute value and send the COMMUNITY attribute with the route
information.
By default, Dell Networking OS does not send the COMMUNITY attribute.
To send the COMMUNITY attribute to BGP neighbors, use the following command.
• Enable the software to send the router’s COMMUNITY attribute to the BGP neighbor or peer group
specified.
CONFIG-ROUTER-BGP mode
neighbor {
ip-address
|
peer-group-name
} send-community
To view the BGP configuration, use the
show config
command in CONFIGURATION ROUTER BGP
mode.
If you want to remove or add a specific COMMUNITY number from a BGP path, you must create a route
map with one or both of the following statements in the route map. Then apply that route map to a BGP
neighbor or peer group.
1.
Enter ROUTE-MAP mode and assign a name to a route map.
CONFIGURATION mode
route-map
map-name
[permit | deny] [
sequence-number
]
2.
Configure a set filter to delete all COMMUNITY numbers in the IP community list.
CONFIG-ROUTE-MAP mode
set comm-list
community-list-name
delete
OR
set community {
community-number
| local-as | no-advertise | no-export |
none}
Configure a community list by denying or permitting specific community numbers or types of
community.
•
community-number
: use AA:NN format where AA is the AS number (2 or 4 Bytes) and NN is a
value specific to that autonomous system.
•
local-AS
: routes with the COMMUNITY attribute of NO_EXPORT_SUBCONFED and are not sent
to EBGP peers.
