Example (IPv6)
OS10(conf-router-template)# address-family ipv6 unicast
OS10(conf-router-bgp-template-af)# allowas-in 5

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
Supported
Releases
10.3.0E or later
show ip bgp l2vpn evpn
Displays the internal BGP routes in the L2VPN EVPN address family in EVPN instances.
Syntax
show ip bgp l2vpn evpn [summary | neighbors [ip-address | interface
interface-type]]
Parameters
summary
Displays a summary of the BGP routes in the L2VPN address family that exchange
with remote VTEPs.
neighbors
Display the remote VTEPs with whom BGP routes in the L2VPN address family
exchange.
ip-address
Displays information about a specific neighbor.
interface
interface-
type
Displays BGP information that is learned through an unnumbered neighbor.
