Example (IPv4)
OS10(config-router-neighbor)# address-family ipv4 unicast
OS10(conf-router-bgp-neighbor-af)# allowas-in 5
Example (IPv6)
OS10(conf-router-template)# address-family ipv6 unicast
OS10(conf-router-bgp-template-af)# allowas-in 5
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
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]
Parameters
summary
Display a summary of the BGP routes in the L2VPN address family that exchange with
remote VTEPs.
neighbors

Default Not congured
Command mode EXEC
Usage information Use this command to display the BGP routes used for the L2VPN EVPN address family in EVPN instances on the
switch.
