set protocols bgp neighbor allowas-in
The set protocols bgp neighbor allowas-in command specifies the number of times that the AS path of a received route can contain the AS number of the recipient BGP speaker and still be accepted. When this configuration is applied to a peer-group, all the neighbors that are part of the peer-group inherit this setting.
The delete protocols bgp neighbor allowas-in command restores the default setting, which is to reject as a loop any route where the path contains the speaker AS number.
Command Syntax
set protocols bgp [vrf <vrf-name>] {neighbor <ip>| peer-group <peer-group> |interface <interface>} {ipv4-unicast|ipv4-labeled-unicast|ipv6-unicast|ipv6-labeled-unicast} allowas-in {<LIMIT>|origin}
delete protocols bgp [vrf <vrf-name>] {neighbor <ip>| peer-group <peer-group> |interface <interface>} {ipv4-unicast|ipv4-labeled-unicast|ipv6-unicast|ipv6-labeled-unicast} allowas-in {<LIMIT>|origin}
Parameter
Parameter | Description |
vrf <vrf-name> | Optional. Specifies a VRF name. The value is a string. It’s a user-defined VRF set by the command set ip vrf <vrf-name> [description <string>]. |
{ipv4-unicast|ipv4-labeled-unicast|ipv6-unicast|ipv6-labeled-unicast} | Specifies the type of the address family. |
neighbor <ip> | Specifies the IPv4/IPv6 address of a peer. |
peer-group <peer-group> | Specifies a peer group. |
interface <interface> | Specifies an L3 interface for BGP connection. The value could be a VLAN interface name, loopback interface name, routed interface or sub-interface name. |
allowas-in {<LIMIT>|origin} | <LIMIT>: Specifies the number of times that the AS path of a received route can contain the AS number of the recipient BGP. Range: 1 to 10. origin: The parameter origin configures BGP to only accept routes originated with the same AS number as the system. This command is only allowed for eBGP peers. |
Example
• This example specifies the number of times that the AS path of a received route can contain the AS number of the recipient BGP speaker and still be accepted.
