Parameters None
Default Not congured
Command mode ROUTER-NEIGHBOR
Usage information To use BGP EVPN service in a VXLAN, you must congure and enable the L2VPN EVPN address family on a VTEP
to support host-based routing to each BGP neighbor.

allowas-in
Congures the number of times the local AS number can appear in the BGP AS_PATH path attribute before the switch rejects the route.
Syntax
allowas-in as-number
Parameters as-number—Enter the number of occurrences for a local AS number, from 1 to 10.
Default Disabled
Command Mode ROUTER-BPG-TEMPLATE-AF
Usage Information Use this command to enable the BGP speaker to accept a route with the local AS number in updates received from
a peer for the specied number of times. This conguration does not apply to updates received from a BGP peer in
a peer group. A BGP peer cannot be assigned to a peer group that is congured with an AS number. The no
version of this command resets the value to the default.
