vrouter-bgp-add
This command adds Border Gateway Protocol (BGP) to a virtual router (vRouter) service on a fabric, cluster, or standalone switch.
Syntax vrouter-bgp-add
vrouter-name name-string |
Specify a name for the vRouter service. |
Specify the following BGP arguments: |
|
neighbor ip-address |
Specify a neighbor IP address to use for BGP filtering. |
l3-port l3port-usable-port name |
Specify the L3 port name for the BGP session. |
remote-as external|internal|-2..4294967295 |
Specify the remote Autonomous System (AS) number. This is a value between 1, and 4294967295. |
local-as external|internal|-2..4294967295 |
Specify the locally configured AS number. This is a value between 1, and 4294967295. |
vrf vrouter-vrf |
Specify the name of the VRF. |
next-hop-self|no-next-hop-self |
Specify if the next-hop is the same router or not. |
prepend|no-prepend |
Specify if you want routers to prepend the local AS to AS_PATH advertisements. |
replace-as|no-replace-as |
Specify if you want to prevent routers from appending the globally configured ASN in outbound BGP UPDATEs toward customer networks that are using the "Local AS" mechanism. This option will append the old ASN instead. |
password password-string |
Specify a password, if desired. |
ebgp-multihop number |
Specify a value for external BGP to accept or attempt BGP connections to external peers, not directly connected, on the network. This is a value between 1, and 255. |
update-source vrouter loopback-interface ip |
Specify the source IP address of BGP packets sent by the router. |
update-source-interface update-source-interface-string |
Specify the source interface of BGP packets sent by the router. This parameter is required for peering over any interface. |
prefix-list-in vrouter prefix-list name |
Specify the prefix list to filter traffic inbound. |
prefix-list-out vrouter prefix-list name |
Specify the prefix list to filter traffic outbound. |
route-reflector-client|no-route-reflector-client |
Specify if a route reflector client is used. |
override-capability|no-override-capability |
Specify if you want to override capability. |
soft-reconfig-inbound|no-soft-reconfig-inbound |
Specify if you want a soft reconfiguration of inbound routes. |
max-prefix max-prefix-number |
Specify the maximum number of prefixes. |
max-prefix-warn-only|no-max-prefix-warn-only |
Specify if you want a warning message when the maximum number of prefixes is exceeded. |
bfd|no-bfd |
Specify if you want BFD protocol support for fault detection. |
bfd-multihop|no-bfd-multihop |
Specify if you want to always use BFD multihop port for fault detection. |
multi-protocol ipv4-unicast|ipv6-unicast|l2vpn-evpn |
Specify a multi-protocol for BGP. |
weight none|weight |
Specify a default weight value between 0, and 65535 for the neighbor routes. |
default-originate| |
Specify if you want to announce default routes to the neighbor or not. |
neighbor-keepalive-interval seconds |
Specify the BGP keepalive interval in seconds. This is a value between 0, and 65535 seconds. |
neighbor-holdtime seconds |
Specify the BGP neighbor hold time in seconds. This is a value between 0, and 65535 seconds. |
connect-retry-interval seconds |
Specify the interval between retrying a connection. The interval can be from 0 to 65535 seconds. |
unnumbered-interop|no-unnumbered-interop |
Specify to enable interoperability between different NetVisor versions for unnumbered BGP neighbors. This option sends both link local address, and the global next hop address even if they are the same. |
route-map-in vrouter route-map name |
Specify the name of the route map for incoming routes. |
route-map-out vrouter route-map name |
Specify the name of the route map for outgoing routes. |
allowas-in|no-allowas-in |
Specify if you want to reject routes with local AS in AS_PATH. Normally, when you do not set this option, nodes reject routes containing their own AS which helps prevent routing loops. However, in some cases nodes that belong to the same AS have no direct connectivity; for example when you form clusters, and choose not to use the cluster link for iBGP communication. In this case the only way to direct routes through connected eBGP neighbors is to set this option so that routes are not rejected from the cluster peer. |
interface vrouter interface nic |
Specify the interface to reach the neighbor. |
advertisement-interval seconds |
Specify the minimal time between sending out BGP routing updates. This is a value between 0, and 600 seconds. The default value is zero (0) seconds. |
description description-string |
Specify a BGP neighbor description. |
Defaults None.

Usage Each fabric, cluster, standalone switch, or virtual network (vNET) can provide tenants with a vRouter service that forwards traffic between networks, and implements Layer 4 protocols. Use this command to add BGP to the vRouter service.
Examples To add BGP to the vRouter service, BGP-vService, the neighbor IP address of 209.75.183.3, remote AS 45, and network address of 172.26.21.7/32, use the following command:
CLI (network-admin@switch) > vrouter-bgp-add vrouter-name BGP-vService neighbor 209.75.183.3 remote-as 45 network 172.26.21.7/32
