Command Mode ROUTER-BGP
Usage
Information
Change the router ID of a BGP router to reset peer-sessions. The no version of this command resets the
value to the default.
By default, OS10 sets a loopback IP address as the router ID. If there is no loopback address, the software
chooses the highest IP address that is configured to a physical interface.
NOTE: To configure these settings for a nondefault VRF instance, you must first enter the ROUTER-
CONFIG-VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
2. From the ROUTER BGP mode, enter the ROUTER BGP VRF mode using the vrf vrf-name
command.
Example
OS10(conf-router-bgp-10)# router-id 10.10.10.40
Supported
Releases
10.3.0E or later
send-community
Sends a community attribute to a BGP neighbor or peer group.
Syntax
send-community {extended | standard}
Parameters
● extended — Enter an extended community attribute.
● standard — Enter a started community attribute.
Default Not configured
Command Mode ROUTER-NEIGHBOR
Usage
Information
A community attribute indicates that all routes with the same attributes belong to the same community
grouping. All neighbors belonging to the template inherit the feature when configured for a template. The
no version of this command disables sending a community attribute to a BGP neighbor or peer group.
Example
OS10(conf-router-neighbor)# send-community extended
Supported
Releases
10.3.0E or later
sender-side-loop-detection
Enables the sender-side loop detection process for a BGP neighbor.
Syntax
sender-side-loop-detection
Parameters None
Default Enabled
Command Mode ROUTER-BGP-NEIGHBOR-AF
Usage
Information
This command helps detect routing loops, based on the AS path before it starts advertising routes. To
configure a neighbor to accept routes use the neighbor allowas-in command. The no version of
this command disables sender-side loop detection for that neighbor.
Example (IPv4)
OS10(conf-router-bgp-102)# neighbor 3.3.3.1
OS10(conf-router-neighbor)# address-family ipv4 unicast
OS10(conf-router-bgp-neighbor-af)# sender-side-loop-detection
