Syntax
sender-side-loop-detection
Parameters None
Default Enabled

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.

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
