Create a new BGP peer group

Availability: This command is available to cluster administrators at the admin privilege level.

Description

The network bgp peer-group create command is used to create a border gateway protocol (BGP) peer group. A BGP peer group will advertise VIP routes for the list of vservers in the peer group's vserver-list using the BGP LIF of the peer group. A BGP peer group will advertise VIP routes to a peer router using the border gateway protocol. The address of the peer router is identfied by the peer-address value.

Parameters

-ipspace <IPspace> - IPspace Name

This parameter specifies the IPspace of the peer group being created.

-peer-group <text> - Peer Group Name

This parameter specifies the name of the peer group being created.

-bgp-lif <lif-name> - BGP LIF

This parameter specifies the BGP interface (BGP LIF) of the peer group being created.

-peer-address <IP Address> - Peer Router Address

This parameter specifies the IP address of the peer router for the peer group being created.

[-peer-asn <integer>] - Peer Router Autonomous number

This parameter specifies the peer router autonomous system number (ASN) in the peer group being created. The default value is the value of the local node's ASN.

-route-preference <integer> - Route Preference

This parameter specifies the preference field in BGP update messages for VIP routes. If a router receives multiple VIP route announcements for the same VIP LIF from different BGP LIFs, it will install the one that has the highest preference value. The default route preference value is 100.

[-asn-prepend-type <ASN Prepend type>] - ASN prepend type (privilege: advanced)

This parameter specifies the ASN that will be prepended in the BGP attributes. The possible values are local-asn and peer-asn . The default behaviour is not to prepend any ASN.

[-asn-prepend-count <integer>] - ASN prepend count (privilege: advanced)

This parameter specifies the number of times ASN, as specified in asn-prepend-type will be prepended in the BGP path attributes. The default behaviour is not to prepend any ASN.

[-community <BGP community>,…​] - BGP Community (privilege: advanced)

This parameter specifies the communities that will be included in the BGP path attributes. The default behaviour is not to include any community in BGP path attributes.

[-med <integer>] - Multi Exit Discriminator (privilege: advanced)

This parameter specifies the Multi Exit Discriminator (MED) attribute of BGP update messages, which can be used by routers for best path selection, in cases where more than one peer advertises the same route with similar attributes.

[-use-peer-as-next-hop {true|false}] - Use Peer Address As Next Hop

This parameter specifies whether the peer group uses the peer address as a next hop route. When the value is true, the peer address is used as the next hop router for packets sent from VIP LIFs via the port on which bgp-lif is configured. Internally, a default route with a gateway configured as the peer-address is added automatically on the node for all the Vservers in this peer group's IPspace. The route will be added for a Vserver only if it has a VIP LIF hosted on the current node of bgp-lif . Note that these automatically installed default routes are for VIP traffic; however, they can be used for non-VIP traffic as well if a Vserver hosts both VIP and non-VIP LIFs in the same subnet as bgp-lif . This route will have metric of 20 and will be used to forward traffic through the current port of bgp-lif . The default value of this parameter is false.
