To allow BGP route updates from peers with the same AS number as the current system AS; run the command set protocol bgp neighbor evpn neighbor allowas-in. This configuration is needed when different BGP peers reside in different locations that cannot be directly connected but they both use the same AS number. Parameter vrf is optional and if not specified then the command will affect the default VRF.
The parameter (1-10) configures the amount value <1-10> configures the number of accepted occurrences of the current system AS number in AS path.
The parameter origin configures BGP to only accept routes originated with the same AS number as that of the current system.
Run the command delete protocol protocols bgp neighbor evpn neighbor allowas-in to remove this configuration.
Command Syntax
set protocol protocols bgp [vrf <text>] [l2vpn] evpn neighbor <bgp-peer>evpn allowas-in ({<1-10> | origin)}
delete protocol protocols bgp [vrf <text>] [l2vpn] evpn neighbor <bgp-peer>evpn allowas-in ({<1-10> | origin)}
Parameter
Parameter | Description |
vrf <text> | Optional. Specifies the name of the VRF. |
l2vpn
| neighbor <bgp-peer> | Specify the BGP peer IPv4 or IPv6 address. |
allowas-in (<1-10>|origin) | Value |
<1- |
10> specifies the number of occurrences of AS in AS path, origin configures BGP to only accept routes originated with the same AS number as that of the system. |
Example
- Configure BGP to accept BGP EVPN route updates from peer peer1 3.3.3.3 in VRF BLUE , for layer 2 EVPN and accept and also the accepted routes originated with the same AS number as the system.
