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
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
