neighbor flowspec redirect

Configures the Border Gateway Protocol flow specification (BGP flowspec) redirect nexthop holder and action type at neighbor or peer-group level.

Syntax

neighbor { ip-address | peer-group } flowspec redirectholder { nrli | extended-community } type { 0x0800 | 0x080c }

no neighbor { ip-address | peer-group } flowspec redirecttype { 0x0800 | 0x080c } holder { nrli | extended-community }

Command Default

By default, BGP flowspec redirect nexthop holder is set to nrli and the action type is set to 0x080c.

Parameters

ip-address

IP address in IPv4 format.

peer-group

Name of a peer group.

holder

Specifies where the IP address of redirect nexthop is encoded in the BGP update packet.

nrli: Specifies encoding as Network Layer Reachability Information (NRLI) in the BGP update packet.
extended-community: Specifies encoding as extended-community information in the BGP update packet.

type

Specifies the extended-community type for the redirect IP nexthop action.

0x0800: Specifies an extended-community type of 0x0800 .
0x080c: Specifies an extended-community type of 0x080c .

Modes

BGP address-family IPv4 flowspec configuration mode

Usage Guidelines

Settings configured by using the neighbor flowspec redirect command only apply to locally-generated BGP flowspec routes; they are not applied to the advertisement of remote routes.

The no form of the command restores the default configuration.

Examples

The following example shows how to specify encoding the nexthop IP address as nrli in the BGP update packet and configure the BGP flowspec redirect nexthop action type as x0800.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 flowspec  
device(config-bgp-ipv4fs)# neighbor 10.61.61.1 flowspec redirect holder nrli next-hop type 0x0800
