Configure Peer Groups

Configure or edit peer groups to create update policies for neighbors in the same group.

Before you begin

  • To perform this procedure on a non-default VRF, you must first change the VRF instance. For information about how to use EDM for a non-default VRF, see Select and Launch a VRF Context View. All parameters might not be available in non-default VRFs.

  • The VRF must have an RP trigger of BGP.

Procedure

  1. In the navigation pane, expand Configuration > IP.
  2. Select BGP.
  3. Select the Peer Groups tab.

    You can modify an existing parameter by double-clicking the value.

  4. Select Insert.
  5. Configure the peer group as required.
  6. Select Apply.

Peer Groups field descriptions

Use the data in the following table to use the Peer Groups tab.

Name

Description

Index

Specifies the index of this peer group.

GroupName

Specifies the peer group to which this neighbor belongs (optional).

Enable

Enables or disables the peer group.

RemoteAs

Configures a remote AS number for the peer-group in the range 0–65535.

DefaultOriginate

When enabled, the BGP speaker (the local router) sends the default route 0.0.0.0 to a group of neighbors for use as a default route. The default is disabled.

DefaultOriginateIpv6

When enabled, the BGP speaker (the local router) sends the default route to a group of neighbors for use as a default route. The default is disabled.

EbgpMultiHop

When enabled, the switch accepts and attempts BGP connections to external peers that reside on networks that do not directly connect. The default is disabled.

AdvertisementInterval

Specifies the time interval, in seconds, that elapses between BGP routing updates. The default value is 30 seconds.

KeepAlive

Specifies the time interval, in seconds, between sent BGP keep alive messages to remote peers. The default value is 60.

HoldTime

Configures the hold time for the group of peers in seconds. Use a value that is three times the value of the KeepAlive time. The default value is 180.

Weight

Assigns an absolute weight to a BGP network. The default value is 100.

MaxPrefix

Limits the number of routes accepted from this group of neighbors. A value of zero indicates no limit The default value is 12,000 routes.

NextHopSelf

Specifies that the switch must set the NextHop attribute to the local router address before sending updates to remote peers.

RoutePolicyIn

Specifies the route policy that applies to all networks learned from this group of peers.

RoutePolicyOut

Specifies the route policy that applies to all outgoing updates to this group of peers.

RouteReflectorClient

Specifies that this peer group is a route reflector client.

Note:

This parameter only applies to VRF 0.

SoftReconfigurationIn

When enabled, the router relearns routes from the specified neighbor or group of neighbors without restarting the connection after the policy changes in the inbound direction. The default value is enable.

Enabling SoftReconfigurationIn stores all BGP routes in local memory (even non-best routes).

MD5Authentication

Enables and disables MD5 authentication. The default is disable.

RemovePrivateAs

Strips (when enabled) private AS numbers when the switch sends an update. The default is enable.

SendCommunity

Enables or disables sending the community attribute of the update message to the specified peer group. The default value is disable.

AfUpdateSourceInterfaceType

Specifies the interface type.

AfUpdateSourceInterface

Specifies the IP address used for circuitless IP (CLIP) for this peer group.

Vpnv4Address

Enables BGP address families for IPv4 (BGP) and Layer 3 VPN (MP-BGP) support. Enable this parameter for VPN/VRF Lite routes.

IpvpnLiteCap

Specifies (when enabled) that IP VPN Lite capability can be enabled or disabled on the BGP neighbor peer. The default is disable.

RouteRefresh

Enables or disables route refresh. If enabled, a route refresh request received by a BGP speaker causes the speaker to resend all route updates in the database that are eligible for the peer that issues the request. This parameter only applies to VRF 0.

AsOverride

Specifies that the AS Override parameter can be enabled or disabled for the BGP peer group. The default is disable.

AllowedAsIn

Specifies the number of AS-in allowed for the BGP peer group. The range is 1–10.

IPv6Cap

Enable or disable the IPv6 capability on the BGP neighbor peer. The default value is disable.

Ipv6RoutePolicyIn

Specifies the policy (by name) that applies to all network IPv6 routes learned from this peer.

Ipv6RoutePolicyOut

Specifies the policy (by name) that applies to all outgoing IPv6 route updates.

Ipv6MaxPrefix

Configures a limit on the number of IPv6 routes accepted from a neighbor.

A value of 0 means no limit exists.

BfdEnable

Enables Bidirectional Forwarding Detection (BFD) for the BGP peer group.
