Connectivity Guide

NOTE: To congure these settings for a non default VRF instance, you must rst 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 congured
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 congured 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 congure 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
Example (IPv6)
OS10(conf-router-bgp-102)# neighbor 32::1
OS10(conf-router-neighbor)# address-family ipv6 unicast
OS10(conf-router-bgp-neighbor-af)# no sender-side-loop-detection
Supported Releases 10.3.0E or later
